Thread: volume

this is my question:
calulate the weight of a piece of plastic, 20cm^3 in volume, if its density is 1.6g/cm^3?

would i do 1.6 x 20 =32 g?

Yeah, that's right.

Of course the question is erroneously describing mass as weight but your answer is fine

if the question was:
calculate the volume of a piece of wood which weighs 102g and has a density of 0.85g/cm^3?

would i do 0.85 x 102 =86.7 cm^3
