Answer 1

The surface area of a cube is 6×side/edge square.
The 6×11 square =726cmsquare

Answer 2

Answer:

TSA of the cube = 726 cm²

Explanation:

Given

edge of a cube (a)=11cm

$\boxed {Surface\: area\: of\: a \:cube \:(T.S.A)= 6a^{2}}$

Now ,

TSA = 6×(11cm)²

= 6 × 121 cm²

= 726 cm²

Therefore,

TSA of the cube = 726 cm²
