Question

Спортивный зал имеет форму прямоугольного параллелепипеда. Его длина равна 80 м, ширина составляет 7/10 от длины , а высота - 20% от ширины. Какова площадь пола зала? Сколько м(кубических) воздуха в зале?

Answer 1

80* 7/10=56м- ширина зала

56*20%=56*0,2=11,2м- высота

80*56=4480 кв.м- площадь пола

80*56*11,2=50176 кубм- столько воздуха

 

 

 

 

 

 

Answer 2

1) 7/10= 80:10*7=56 м ширина

2)20%= 56:100*20= 11,2 м высота

3) S пола=80*56= 4480 м (квадратных) площадь пола зала

4) 4480*11,2= 50176 м ( кубических) обьем зала

Answer 3

Calculation of the Floor Area of the Gym

To calculate the floor area of the gym, we need to multiply the length and width of the rectangular parallelepiped.

Given: - Length of the gym = 80 m - Width of the gym = 7/10 * length - Height of the gym = 20% of the width

Let's calculate the width and height first:

Width = 7/10 * 80 m = 56 m Height = 20% of 56 m = 0.2 * 56 m = 11.2 m

Now, we can calculate the floor area:

Floor Area = Length * Width = 80 m * 56 m = 4480 square meters

Therefore, the floor area of the gym is 4480 square meters.

Calculation of the Volume of Air in the Gym

To calculate the volume of air in the gym, we need to multiply the floor area by the height of the gym.

Given: - Floor area of the gym = 4480 square meters - Height of the gym = 11.2 m

Let's calculate the volume:

Volume = Floor Area * Height = 4480 square meters * 11.2 m = 50176 cubic meters

Therefore, the volume of air in the gym is 50176 cubic meters.

Please note that the calculations provided are based on the given information and assumptions.
