Question

Below is a pattern that can be used to cut out and fold to make a cube. If each edge is 5 inches, what will be the surface area of the cube? A 30 in? B 120 in С 150 in? D 3,125 in

Answer 1

In words, the surface area of a cube is the area of the six squares that cover it. The area of one of them is a*a, or a^2

`A=6a^2`

Here, a = 5 inches

`\begin{gathered} A=6\cdot(5^2) \\ A=6\cdot25 \\ A=150 \end{gathered}`

The answer would be 150 in^2
