The truck brought 1.5 tons of sand. What area of the yard can be covered with this sand with a layer thickness of 5 cm?

These tasks: m (mass of sand brought by a truck) = 1.5 t (in SI m = 1500 kg); h (thickness of the sand layer in the yard) = 5 cm (in SI h = 0.05 m).

Constants: according to the condition ρp (density of the brought sand) = 1500 kg / m3.

The area of the yard, which it turned out to be covered with the brought sand, can be expressed from the formula: V = S * h = m / ρп, whence S = m / (ρп * h).

Let’s make a calculation: S = 1500 / (1500 * 0.05) = 20 m2.

Answer: You can fill up 20 m2 of the yard with the brought sand.
