Question

A block of foam has a mass of 10 g, a volume of 60 cm3, and a length of 30 cm. What is the density of the foam? (If necessary, round your answer to three decimal places.)

Answer 1

The density is

(Mass)/(volume)

= 10/60 = 1/6 g/cm^3 . (1.667)

If you already know the volume, then the length doesn't matter.

Answer 2

10g/ 60cm^3 = 1g/6ml = 0.167g/ml 

(1 cm^3 = 1 ml )
