Question

Each edge of a cube measures 4.7 in. What is the surface area of the cube? Enter your answer, as a decimal, in the box.

Answer 1

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

Answer 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.
