A car with a carrying capacity of 3 tons must transport sand with a volume of 40m3.

A car with a carrying capacity of 3 tons must transport sand with a volume of 40m3. How many flights will it take to do this? If the sand is 1500kg / m3.

Initial data: M (vehicle carrying capacity) = 3 t = 3,000 kg; V (volume of sand for transportation) = 40 m ^ 3.

Reference data: according to the condition ρ (sand density) = 1500 kg / m ^ 3.

1) Determine the mass of sand for transportation:

m = ρ * V = 1500 * 40 = 60,000 kg.

2) Let’s calculate the required number of trips taking into account the maximum load of the car:

N = m / M = 60,000 / 3,000 = 20 flights.

Answer: With a maximum load for transportation of 40 m ^ 3 of sand, a car will need to perform 20 trips.
