Question

Find the surface area of a cube whose edge is 11 cm.

Answer 1

Answer:

726 cm²

Step-by-step explanation:

Edge = 11 cm

∴ Surface Area = 6 × (side)²

                          = 6(11)² cm²

                          = 6 × 121 cm²

                          = 726 cm²

Answer 2

$\huge\mathfrak{Answer:-}$

Given ;-

• Edge = 11 cm

Now,

We know that ;

Surface Area = 6 × {Side}^2

So,

=> 6 × {11cm}^2

=> 6 × 121 cm^2

=> 726 cm^2

Hence,

Answer = 726 cm^2
