Question

Find the surface area of a cube with a side length of 8 m

Answer 1

Step-by-step explanation:

Length= 8m

Surface area = ?

Now ,

$Surface \: area =6 {l}^{2}$

= 6 × 8 × 8

= 6 × 64

$= 384 {m}^{2}$

Answer 2

Answer:

384 m²

Step-by-step explanation:

The formula to find the surface area of a cube is:

S.A. = 6a²

Here,

a ⇒ length of a side ⇒ 8m

Let us solve it now.

S.A. = 6a²

S.A. = 6 × 8 × 8

S.A. = 48 × 8

S.A. = 384 m²
