Question

10.

Consider the cube shown below.
KV
X + 3
Find the surface area of the cube.
Give your answer in expanded form.

Answer 1

• Given, side (a) = x+3
• We know, surface area of a cube = 6a^2
• Therefore, the surface area of the cube

`6(x + 3) ^(2) \\ = 6( {x}^(2) + 6x + 9) \\ = 6 {x}^(2) + 36x + 54`

Answer:

The answer is

`{6x}^(2) + 36x + 54`

Hope it helps.
