Question

find, total Surface of area of a cube L=12​

Answer 1

Answer:

864 sq.m

Step-by-step explanation:

If l = 12, then to find area of one face of cube, use the formula 'side × side'.

As we know, that one face of a cube is a square.

So, area of one face of cube = 12 × 12 = 144 sq.m

To find surface area of the cube, multiply 144 sq.m by 6 as a cube has 6 faces.

= 144 × 6 = 864 sq.m

Therefore, the surface area of cube is 864 sq.m

Answer 2

Answer:

Tsa Of cube =

$6a ^{2}$

so, Tsa of cube

$= { 6(12)}^{2}$

$= 6 \times 144$

$= 864 {m}^{2}$
