Three cubes – marble, ice and brass – have the same volume. Which one has the greatest mass, which one has the smallest?

Since all three cubes have the same volume, and the formula for calculating body mass is: m = ρ * V, the cube with the highest density value will have a larger mass, and the cube with the lowest value will have a smaller mass.

According to the density table of substances:

ρ1 (marble) = 2700 kg / m ^ 3; ρ2 (ice) = 900 kg / m ^ 3; ρ3 (brass) = 8500 kg / m ^ 3.

Comparison: m2 (ice) <m1 (marble) <m3 (brass).

Answer: The brass cube has the greatest mass, and the ice cube has the smallest mass.
