Question

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

Answer 1

The density is:
`0.926 \,(g)/(cm^3)`

Step-by-step 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=(mass)/(Vol) =(25)/(27) \,(g)/(cm^3) \approx 0.926 \,(g)/(cm^3)`
