Volume of the aluminum cube = (20.00 g) / (2.70 g ml⁻¹) = 20.00/2.70 ml = 20.00/2.70 cm³
Edge of the aluminum cube = ∛(20.00/2.70) cm = 1.95 cm
Dimensions of the cube = 1.95 cm × 1.95 cm × 1.95 cm
Edge of the aluminum cube = ∛(20.00/2.70) cm = 1.95 cm
Dimensions of the cube = 1.95 cm × 1.95 cm × 1.95 cm
