The measure of an edge of a cube = 4.7 in
We have to determine the surface area of the cube.
The surface area of a cube is the area of the six squares that cover it. The area of one square is
. Therefore, area of six squares =
.
Surface area of cube =
, where a is the edge of a cube
Therefore, Surface area of this cube
=

=

= 132.54 square inches.
Therefore, surface area of the cube is 132.54 square inches.
