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
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 [tex] a^{2} [/tex]. Therefore, area of six squares = [tex] 6a^{2} [/tex].
Surface area of cube = [tex] 6a^{2} [/tex] , where a is the edge of a cube
Therefore, Surface area of this cube
= [tex] 6a^{2} [/tex]
= [tex] 6 \times (4.7)^{2} [/tex]
= 132.54 square inches.
Therefore, surface area of the cube is 132.54 square inches.
