Question

A metal cube measures 15 cm on a side and has a density of 6920 kg/m^3. Find the mass in grams.

Answer 1

Mass of the cube is 23350 grams.

Step-by-step explanation:

It is given that,

Side of cube, a = 15 cm = 0.15 m

Density of the cube,
`d=6920\ kg/m^3`

We need to find its mass. It can be calculated using the formula of density as :

`d=(m)/(V)`

`m=d* V`, V is the volume of cube

`m=d* a^3`

`m=6920\ kg/m^3* (0.15\ m)^3`

m = 23.35 kg

or

m = 23350 grams

So, the mass of the metal cube is 23350 grams. Hence, this is the required solution.
