Step-by-step explanation:

Answer 2

The surface area of a cube with side of length 3 units is 54 sq. units.

How to find the surface area of a cube?

Suppose that the cube in consideration has its side of 'a' units length.

Then, the surface area S of that cube is:

$S = 6(a^2) \: \rm unit^2$

For this case, the considered cube has side of length 3 units.

Thus, we get its surface area as;

$S = 6(a^2) = 6(3^2) = 6 \times 3\times 3 = 54 \: \rm unit^2$

Thus, the surface area of a cube with side of length 3 units is  54 sq. units.
