Question

Ширина комнаты,имеющей форму прямоугольного параллелепипеда,5м,длина6м,высота 3м. Найди объём комнаты,площадь пола,площадь потолка и площадь всех стен,считая окна и двери частью стен

Answer 1

Размеры комнаты:
Длина = 6м
Ширина = 5м
Высота = 3м
Решение:
1) 6 * 5 * 3 = 90(куб.м) - объём комнаты
2) 6 * 5 = 30(кв.м) - площадь пола
3) 6 * 5 = 30(кв.м) - площадь потолка
4) 2(5 * 3 + 6 * 3) = 2(15 + 18) = 2 * 33 = 66(кв.м) - площадь всех стен.
Ответ: по 30кв.м - площадь пола и потолка; 66кв.м - площадь всех стен; 90куб.м - объём комнаты

Answer 2

Calculating the Volume of the Room

To calculate the volume of a rectangular parallelepiped room, you need to multiply its length, width, and height. In this case, the length is 6 meters, the width is 5 meters, and the height is 3 meters.

The formula for calculating the volume is:

Volume = Length × Width × Height

Substituting the given values:

Volume = 6m × 5m × 3m = 90 cubic meters

Therefore, the volume of the room is 90 cubic meters.

Calculating the Floor Area

The floor area of a rectangular room can be found by multiplying its length and width. In this case, the length is 6 meters and the width is 5 meters.

The formula for calculating the floor area is:

Floor Area = Length × Width

Substituting the given values:

Floor Area = 6m × 5m = 30 square meters

Therefore, the floor area of the room is 30 square meters.

Calculating the Ceiling Area

The ceiling area of a rectangular room is the same as the floor area. In this case, the ceiling area is also 30 square meters.

Calculating the Wall Area

To calculate the wall area, we need to find the total area of all four walls. Each wall's area can be calculated by multiplying its height by the length of the corresponding side.

The formula for calculating the wall area is:

Wall Area = 2 × (Length × Height + Width × Height)

Substituting the given values:

Wall Area = 2 × (6m × 3m + 5m × 3m) = 2 × (18 square meters + 15 square meters) = 2 × 33 square meters = 66 square meters

Therefore, the total wall area of the room, including windows and doors, is 66 square meters.

Conclusion

In summary, for a room with a length of 6 meters, a width of 5 meters, and a height of 3 meters: - The volume of the room is 90 cubic meters. - The floor area is 30 square meters. - The ceiling area is 30 square meters. - The total wall area, including windows and doors, is 66 square meters.
