**How To Find Volume With Mass And Density** – Learn how to calculate the density, mass, or volume of a solid object with this handy visual tool

The density? Density is a measure of how compact (dense) an object is. If an object has a higher density than water, the object will sink when in water. If it has a lower density than water, it will float. Simple.

## How To Find Volume With Mass And Density

To calculate the density of an object, we need to know the mass and volume of the object. We can then plug these values into the following equation to calculate the density of the object:

The density-mass-volume triangle (shown above) is a visual tool that 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 upper part and mass and volume occupying the two lower parts.

The positions of each element of the triangle show us how they relate to each other through the above formula (

If we want to calculate the density, we just hide the density in the triangle and see what remains. Since mass is greater than volume, we divide the mass by the volume to get the density.

If we want to calculate the mass, we just hide the mass in the triangle and see what remains. Since density and volume go hand in hand, we multiply density by volume to get mass.

If we want to calculate the volume, we just cover the volume in the triangle and see what remains. 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 does not state the volume, so we need to calculate the volume of the box before we can determine the density.

Since the box is a cuboid, the volume can be found by multiplying the lengths of the three sides:

Density = Mass / Volume ρ = m / V ρ = 200 / 120 ρ = 1.67 g/cm³

## Solved] Can Someone Help Me Find The Uncertainty Of The Density Of Water…

Question: How much mass 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 density, m is mass and V is volume. Density (p) is equal to mass (m) divided by volume (V).

Since there are three elements in the formula, 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

### Example Mass, Volume Density Problems

If you’ve ever been fooled by the old question, “What 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 (er, one pound), their density is very different, and we can sometimes mentally confuse weight and density – even though they are different concepts. So – hey – don’t feel dense. Read on to learn exactly what specific gravity is, how it works, and how to calculate specific gravity.

Density is mass by volume – not just direct 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 guided. At equal size (volume), lead weighs much more than feathers (mass).

Density can also be thought of as the degree of compression or compression of a substance. A pound of feathers is full of air space, so it is not very dense at all, while a pound of lead feels much stronger, therefore more dense. This is why you should never comment on your Aunt Mabel’s sponge cake as dense: she was probably looking for something a little more airy.

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 more 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 keep an eye on your units: it’s common 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 mathematics as the symbol p or D. Mass can be written as m, and volume can be written as v. So if you want to get fancy, the formula looks like this:

(Volume is related to space filling: check our volume and weight guide and our volume calculator if you’re not sure.)

So if you have a kilogram of cheese with a volume of 0.0002 m³, not only do you have strange and wonderful dreams, but you also have a cheese with a density of 5000 kg / m³ (p = 1 kg ÷ 0.0002 m³).

Why not fill your tub and try different materials to see what floats or sinks? No electricity, please. ⚡

Water has a density of 1000 kg/m³, so everything that floats in water has a lower density than that, and everything that sinks has a higher density (for example, cooking oil is about 920 kg / m³; tin is 7310 kg / m³; cork). is 240 kg/m³; and Airgel, one of the least dense solids we know, has a density of 1 kg/m³). So how come people float so easily in the Dead Sea? Because it’s not just water. It contains an incredibly high amount of salt, creating an overall density of 1240 kg / m³.
