A rectangular room 8m long by 5m wide contains 120m3 of air. Calculate the height of the room

120 m^3 / (8 m * 5 m)

To calculate the height of the room, we can use the formula for the volume of a rectangular prism:

Volume = length × width × height

Given that the room's dimensions are 8m by 5m and the volume is 120m^3, we can substitute these values into the formula:

120 = 8 × 5 × height

Simplifying the equation:

120 = 40 × height

Now, we can isolate the height by dividing both sides of the equation by 40:

120 / 40 = height

Therefore, the height of the room is:

3 = height

So, the height of the room is 3 meters.

To calculate the height of the room, we can use the formula for the volume of a rectangular box:

Volume = Length x Width x Height

In this case, we know the volume of the room is 120m^3, the length is 8m, and the width is 5m. We need to find the height.

Substituting the given values into the formula, we get:

120 = 8 x 5 x Height

To solve for the height, divide both sides of the equation by (8 x 5):

120 / (8 x 5) = Height

Simplifying the equation gives:

120 / 40 = Height

Therefore, the height of the room is:

Height = 3 meters
