Question

Объём комнаты равен 60 м в кубе.высота комнаты 3 м,ширина 4 м. найдите длину комнаты и площади пола ,потолка, стен

Answer 1

V=abc   a=v/bc =60/(3*4)=5м
5*4=20 м кв площадь пола и потолка
3*4=12 м кв  площадь стены 1
3*5=15 м кв  площадь стены 2
S=(12+15)*2=54 м кв  общая площадь стен

Answer 2

Calculation of Length, Floor Area, Ceiling Area, and Wall Area

To find the length of the room, we can use the formula for calculating the volume of a rectangular prism:

Volume = Length x Width x Height

Given that the volume of the room is 60 cubic meters, the height is 3 meters, and the width is 4 meters, we can rearrange the formula to solve for the length:

Length = Volume / (Width x Height)

Substituting the given values:

Length = 60 / (4 x 3) = 5 meters

Therefore, the length of the room is 5 meters.

To calculate the floor area, we multiply the length and width of the room:

Floor Area = Length x Width

Substituting the given values:

Floor Area = 5 x 4 = 20 square meters

Therefore, the floor area of the room is 20 square meters.

The ceiling area is equal to the floor area since the room is a rectangular prism:

Ceiling Area = Floor Area = 20 square meters

To calculate the wall area, we need to find the perimeter of the room and multiply it by the height:

Perimeter = 2 x (Length + Width)

Substituting the given values:

**Perimeter = 2 x (5 + 4
