Question

A cube measures 3 cm on each side and has a mass of 25 g. What is its density.

Answer 1

Answer:

The density is:   $0.926 \,\frac{g}{cm^3}$

Explanation:

Recall that density is defined as the quotient of the object's mass divided by volume. So, we calculate the volume of the 3 cm side cube:

$Vol = (3 \,cm)^3 = 27 \,\,cm^3$

then the density becomes:

$density=\frac{mass}{Vol} =\frac{25}{27} \,\frac{g}{cm^3} \approx 0.926 \,\frac{g}{cm^3}$
