Well its quite easy: Density=Mass/Volume Volume=Mass/Density SO if mass and density of a cube are given you can easily find its volume.

The formula for density: density = mass / volume. Volume of a cube = edge3 You could then need to find the mass of the cube and substitute the values into the density formula.

You measure its mass and volume and then density = mass/volume.

You need to find the mass and you need to find the volume. The latter may be calculated from the length of the side of the cube. Then, density = Mass/Volume in the appropriate measurement units.

LXWXH= volume find the mass and divide it with the volume mass divided by volume equals density

To solve this you need to know the relationship that density = mass divided by volume We're given a length of a side of a cube as 2.5cm so to find the volume of the cube we need to cube it (length x bredth x height) volume = (2.5)3 = 15.625cm3 so if density = mass(136.95g)/volume(15.625cm3) density = 8.7648 g cm-3 in textbooks its given as (8.3- 8.7 gcm-3) as a typical density of brass.

Since density = mass / volume,volume = mass / density.

The side length is the cube root of the volume.

Find the cube root of the volume. Volume of a cube = length of side^3 therefore length of side = volume^(1/3)

Density is the mass divided by the volume.

Multiply them: density*volume = mass
