A solid cube of aluminum is 1.5cm on each edge. The density of aluminum is 2700kgm\(^{-1}\). Find the mass of the cube.

Density = \(\frac{\text{mass}}{\text{volume}}\)

Volume of solid cube = s\(^3\) = 1.5\(^3\) = 3.375cm\(^3\)

Density = 2700kgm\(^{-3}\) ⇒ 2.7gcm\(^{-3}\)

2.7 = \(\frac{\text{m}}{3.375}\)

mass of the cube = 2.7 x 3.375 = 9.1125g \(\approxeq\) 9.1g
