What is the mass of a pine cube with a side of 1 dm?

We calculate the mass of a pine cube using the formula:

m = ρ * V, where m is the sought mass of the pine cube (kg / m3), ρ is the conditional density of the pine (ρ = 400 kg / m³), V is the volume of the pine cube (V = a3, where a is the length of the edge of the cube ( a = 1 dm = 0.1 m)).

Let’s calculate the mass of a pine cube:

m = ρ * V = ρ * a3 = 400 * 0.13 = 0.4 kg = 400 g.

Answer: A pine cube has a mass equal to 400 g.
