The truck body is filled with sand, the mass of which is 3 tons. what area can be covered with this sand so that the thickness of the coating is 2.5 cm? sand density 1500kg / m ^ 3

We find the volume of sand using the ratio between the volume V, mass m and density ρ:

m = ρV

V = m / ρ = (3000 kg) / (1500 kg / m ^ 3) = 2 m ^ 3.

On the other hand, the volume of the sand layer is equal to the product of the area S and the layer thickness d:

V = Sd;

S = V / d = (2 m ^ 3) / (0.025 m) = 80 m ^ 2.

Answer: 80 m ^ 2.
