Question

The table below shows the dimensions of two colored cubes.


Dimensions of Cubes
Cube Side (cm) Mass
(g)
Blue 5 250
White 4 320

Which cube is denser?
a) Blue, because the ratio of its mass and side is higher.
b) White, because the ratio of its mass and side is lower.
c) Blue, because it has more volume and less amount of matter.
d) White, because it has less volume, but a lot more matter.

Answer 1

b) White, because the ratio of its mass and side is lower.

Density is mass divided by volume, so a lower ratio of mass to side indicates higher density. Since the white cube has a lower ratio of mass to side compared to the blue cube, it is denser.
