Answer

Problem

Find its area if a cube has a side length of 8 units.

Step

Given that the side length (s) is

\$8\$ units

Formula:

The formula for the surface area of a cube with a side length "s" is:

Area = \$6 \times(s)^2\$

Formula:

Subtitute the values

\$6 \times(8)^2\$

\$6 \times 64\$ = \$384\$

Step

So, the area of the cube is

\$384\$ sq.units
