How To Find Volume With Density And Mass – Learn how to calculate the density, mass, or volume of a solid object with this handy visual tool
Density? Density is a measure of how compact (dense) an object is. If an object has a greater density than water, the object will sink when in water. If it is less dense than water, it will float. Simple.
How To Find Volume With Density And Mass
To calculate the density of an object, we need to know the object’s mass and volume. We can then plug these values into the following equation to calculate the object’s density:
How To Calculate Density
The density-mass-volume triangle (pictured above) is a visual tool we can use to calculate the density, mass, or volume of a solid object if we know the remaining two values. The triangle is divided into three parts, with density occupying the top part and mass and volume occupying the bottom two parts.
The positions of each element of the triangle show us how they are related to each other through the above formula (
If we want to calculate the density, we just cover the density in the triangle and see what is left. Since mass is over volume, we divide mass by volume to get density.
If we want to calculate the mass, simply cover the mass in the triangle and see what is left. Since density and volume go hand in hand, we multiply density times volume to get mass.

If we want to calculate the volume, simply cover the volume in the triangle and see what is left. Since mass is greater than density, we divide the mass by the density to get the volume.
However, the question states the mass of the box but not the volume, so we need to work out the volume of the box before we can determine the density.
Since the box is a cube, the volume can be found by multiplying the lengths of the three side lengths together:
Density = Mass / Volume ρ = m / V ρ = 200 / 120 ρ = 1.67 g/cm³

Question: A container is a rectangular prism. Its dimensions are 50 cm X 40 cm X 10 cm. If it is full of water, what is the mass of the water?
Question: A block of wood is a rectangular prism. Its length is 8 cm, the length of one of the two perfect square sides is 2 cm, the mass of the wooden block on the electronic scale reads 150 grams, what is the density of the wooden block?
What Is Volume In Chemistry?
Question: How much mass is in a rectangular prism with a height of 100 and a length of 25 and a width of 3?
Answer: First find the volume by multiplying the numbers together to give 7500. Now multiply this answer by the density of the rectangular prism to give the mass. The formula for calculating density is p = m/V, where p is the density, m is the mass, and V is the volume. Density (p) equals mass (m) divided by volume (V).
Since the formula has three elements, it can be expressed in other ways depending on the element you want to calculate.
To calculate density: p = m/V To calculate mass: m = pV To calculate volume: V = m/p

If you’ve ever been fooled by the age-old question, “Which weighs more: a pound of feathers or a pound of lead?” then I wouldn’t be alone. Although feathers and lead weigh exactly the same (ahem, one pound), their densities are very different, and sometimes we can mentally confuse weight and density—even though they are different concepts. So – hey – don’t feel thick. Read on to find out exactly what density is, how it works, and how to calculate density.
Density is mass per volume – not just straight mass. So if the question was, “Which weighs more: a 500ml jug full of feathers or a 500ml jug full of lead?” then the answer would be a guide. For the same space it takes up (volume), lead weighs much more than feathers (mass).
Density can also be thought of as a compact or compressed substance. A pound of feathers is full of air space, so it’s not very dense at all, while a pound of lead feels much firmer, so it’s denser. This is why you should never comment on your Aunt Mabel’s sponge cake, describing it as dense: she probably went for something a little airier.
Density is also what makes things float or sink. When two or more substances are mixed, the denser substance sinks to the bottom, while the less dense substance is buoyant and floats to the top. Try mixing oil and water and see how they separate into layers, with the less dense oil on top.

Always be aware of your units: the default is to use g or kg for cm³ or m³, so use our unit converters if your measurements are in different units.
Density is often written in math as the symbol p or D. Mass can be written as m, and volume can be written as V. So, if you want to be fancy, the formula looks like this:
(Volume has to do with filling up space: check out our volume and weight guide and our volume calculator if you’re still unsure.)
So if you have a kilogram of cheese with a volume of 0.0002 m³, then not only are you in for some weird and wonderful dreams, but you also have cheese with a density of 5000kg/m³ (p = 1kg ÷ 0.0002m³) .

Why not fill the bath and try different materials to see what floats or sinks? Just no electricity, please. ⚡
Water has a density of 1000 kg/m³, so anything that floats in water has a lower density than that, and anything that sinks has a higher density (eg cooking oil is about 920 kg/m³; tin is 7310 kg/m³; cork is 240 kg/m³; and Aerogel, one of the least dense solids we know, has a density of 1kg/m³). So how do people navigate the Dead Sea so easily? Because it’s not just water. It has an incredibly large amount of salt, creating a general density of 1240kg/m³. Volume is a measure of the amount of space that matter occupies. Matter is defined as a physical substance that occupies space and has mass.
Easy Ways To Calculate The Concentration Of A Solution
In physical sciences such as chemistry, the standard unit of volume is the cubic meter (m3). From this, other units are derived including liter (L) and milliliter (mL). Because chemical experiments usually involve relatively small amounts of liquid solutions, it is more common to express volume in milliliters rather than cubic meters.
Many aspects of chemistry require volume to be measured with a high degree of accuracy. It is vital for determining the composition of sample substances, for example, or when synthesizing various chemical compounds.
Unlike mass, volume can change depending on factors such as the state of matter, temperature, and pressure. For example, the volume of a gas depends on the volume of its container. Even solid objects like cotton or Styrofoam can shrink due to voids in their macroscopic proportions.
Such variability means that a more precise definition of volume is required. This is usually determined by certain parameters such as temperature and pressure. Any changes to these settings will also change the volume.
Density Mass Volume
In science, volume is a measure of the amount of three-dimensional space an object occupies. It is usually measured in cubic meters based on the SI or metric system.
Volume can be represented by three axes – length, width and height. However, in practice, volume in chemistry is commonly measured in liters and milliliters. This is because most laboratory experiments in chemistry use solutions, liquid mixtures, and suspensions.
Accurate volume measurement is critical to ensure accurate chemical reactions and reaction rates. It is important for both chemical analysis and synthesis of chemical substances.
But while measuring the volume of solids (even irregularly shaped ones) and liquids is relatively easy, measuring gas is more problematic.

The volume of a gas is directly dependent on its container, that is, a fixed volume cannot be specified without reference to the volume of the container. However, the volume of a gas is always directly proportional to temperature and inversely proportional to pressure. See a summary of gas laws below:
There are many ways to calculate the volume of a substance. The most appropriate method will depend on the state of matter and other factors, such as temperature and pressure.
For solids and liquids, calculating volume is relatively simple. If you know the density
