Question

A 2.8-kg pile of aluminum (rho = 2.70 g/cm3) cans is melted, then cooled into a solid cube. What is the volume of the cube?

Answer 1

Step-by-step explanation:

mass of aluminum 2.8 kg = 2.8 x 1000 = 2800 g

ρ = density of aluminum given = 2.7 g / cm³

density = mass / volume

volume = mass / density

= 2800 / 2.7

= 1037 cm³

So volume of cube required = 1037 cm³.
