Question

The area of the floor of a cubical room is 49


`{m}^(2)`
Find the area of 4 walls

​

Answer 1

A cubical is a 3D square where all the sides are the same length.

The area of the floor is 49 square metered.

Since all sides are equal the area of the walls would also be 49 square meters each.

The area of the 4 walls would be 49 x 4 = 196 square meters.

Answer 2

Explanation:

Since its a cube, Area of Floor = Area of Wall (Area of Square)

Area of 1 wall =

`49 {m}^(2)`

Area of 4 walls =

`49 * 4 \\ = 196 {m}^(2)`
