The volume of a room is 80 m3. The area
of the floor is 20 m2. The height of the
room is
(a) 1 m
(6) 2 m
(c) 3 m
(d) 4 m.​

Answer 1

Given:

The volume of the room is= 80 m³

The area of the floor is = 20 m³

To find:

The height of the room.

Solution:

We know that the volume of the room must be:

Volume = length× breadth × height

volume = area × height

On substituting the values in the equation, we get:

80 = 20 × height

height = 80/20

height = 4 m

Thus, the height of the room will be 4 m.
