Question

Find the surface area of the cube shown.

Answer 1

A=6a^2

A=6(5.5)^2

A=181.5

Hopefully I answered correctly.

Answer 2

As we know that surface area of the cube is given by the formula

Surface Area (SA)=$6a^2$

where a is the side length of the cube .

As we can see in the diagram the side length of the cube is $a=5.5cm$

Hence the surface area of the cube will be

$SA=6*(5.5)^2\\\\SA=6*30.25 cm^2=181.5 cm^2$
