There are 6 faces and area of each face = 4.7^2

so surface area of the whole cube = 6 * 4.7^2 = 132.54 in^2

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
a^(2). Therefore, area of six squares =
6a^(2).

Surface area of cube =
6a^(2) , where a is the edge of a cube

Therefore, Surface area of this cube

=
6a^(2)

=
6 * (4.7)^(2)

= 132.54 square inches.

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