The truck body has the shape of a rectangular parallelepiped with dimensions of 125 cm, 80 cm and 500 cm. How many rails does a truck have to travel to transport 35 m³ of sand?

Brief record of the task.
Truck body dimensions:
a = 125 cm,
b = 80 cm,
s = 500 cm,
35 m ^ 3 sand -? flights.
1. Let’s calculate the volume of the car body:
V = a b c = 125 80 500 = 5,000,000 cm ^ 3.
2. Let’s represent the value of volume in m ^ 3:
in 1 m ^ 3 – 1,000,000 cm ^ 3, 5,000,000 cm ^ 3 – 5 m ^ 3.
3. Let’s calculate the number of flights:
35: 5 = 7.
Answer: to transport a given amount of sand, you need to make 7 flights.
