The mass of 10 cm3 of pine is equal to 4 g. Find the mass of a pine cube, the length of the edge of which is 10 cm.

Let’s calculate the density of pine, for this we divide its mass by volume:

4: 10 = 0.4 kg / m ^ 3.

Let’s find the volume of a cube with an edge of 10 cm:

10 * 10 * 10 = 1000 cm ^ 3.

Then, in order to find its mass, it is necessary to multiply the volume by the density found earlier:

1000 * 0.4 = 400 g.
