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

Answer:

Mass of the cube is 23350 grams.

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 :

$d=\dfrac{m}{V}$

$m=d\times V$, V is the volume of cube

$m=d\times a^3$

$m=6920\ kg/m^3\times (0.15\ m)^3$

m = 23.35 kg

or

m = 23350 grams

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