Question

Кузов автомобиля,имеющий форму прямоугольного параллелепипеда с измерениями 2,5 м, 3 м и 0,7 м,заполнен зерном.Определите массу зерна в кузове,если 10м в кубе имеют массу 8ц.

Answer 1

2,5*3*0,7/10*8=4,2 м³

Answer 2

Calculation of Grain Mass in the Car Body

To determine the mass of grain in the car body, we need to calculate the volume of the car body and then multiply it by the mass of grain per cubic meter.

Given: - Length of the car body (L) = 2.5 m - Width of the car body (W) = 3 m - Height of the car body (H) = 0.7 m - Mass of grain per cubic meter (M) = 8 tons (or 8,000 kg)

Calculation Steps:

1. Calculate the volume of the car body: - Volume (V) = Length (L) x Width (W) x Height (H)

2. Multiply the volume by the mass of grain per cubic meter to get the total mass of grain in the car body: - Mass of grain = Volume x Mass of grain per cubic meter

Let's calculate the mass of grain in the car body using the given dimensions and mass of grain per cubic meter.

Calculation:

1. Calculate the volume of the car body: - Volume (V) = 2.5 m x 3 m x 0.7 m - Volume (V) = 5.25 cubic meters

2. Multiply the volume by the mass of grain per cubic meter: - Mass of grain = 5.25 cubic meters x 8,000 kg/cubic meter - Mass of grain = 42,000 kg

Therefore, the mass of grain in the car body is 42,000 kg.

Please note that the calculation assumes a uniform distribution of grain within the car body and does not take into account any additional factors such as the weight of the car body itself or the density of the grain.
