How many trips should a car with a carrying capacity of 3 tons make to transport 20 m3

How many trips should a car with a carrying capacity of 3 tons make to transport 20 m3 of cement, the density of which is 2800 kg / m3?

Let’s calculate the mass of 20 m3 of cement:

m = ρ * V, where m is the mass of cement (kg), ρ is the density of cement (ρ = 2800 kg / m³), V is the volume of cement for transportation (V = 20 m³).

Let’s calculate the mass of 20 m3 of cement:

m = ρ * V = 2800 * 20 = 56000 kg.

The number of trips to be made by the car:

N = m / m1, where m1 is the carrying capacity (m1 = 3 t = 3000 kg).

N = m / m1 = 56000/3000 = 18.67 (round up to the nearest higher integer, 19 flights).

Answer: To transport cement, a car must make 19 trips.
