Question

A cube of pure aluminum is measured and found to have a masa of 250 kg and a length of .4524 m, what is the density of the sample in grams per cubic centimeters?

Answer 1

ρ = M / V density of object

ρ = 250 kg / (.4524 m)^3

ρ = 250 kg * 1000 g/kg / [.0926 m^3 * 10^6 cm^3/m^3]

ρ = 2.5E5 g / 9.26E4 cm^3 = 2.7 g/cm^3
