Question

Here is a picture of a cube, and the net of this cube.

What is the surface area of this cube?

Answer 1

726

Explanation:

Answer 2

The surface area of the net of cube is 726 sq cm

The surface area of the cube is 484 sq cm

Explanation:

Here we need to find out the surface area of net of a cube and a cube

Given,

Each side of the cube is 11 cm

The net of a cube consists of 6 squares.

Formula

The surface area of the net of the cube = 6 X ( area of each square)

= 6 X ( 11 X 11) sq cm

= 726 sq cm

Now, the surface area of a cube = lateral surface area of the cube

Formula

The lateral surface area of the cube = 4 X
`side^(2)`

= 4 X
`11^(2)` sq cm

= 484 sq cm

Hence the surface area of the net of a cube and only a cube is different.
