Question

a square box is being cut apart and has a measurement system below. What is the surface area of the box?

Answer 1

73.5 in²

Step-by-step explanation

To find the surface area, we have to find the area of one face - one of the squares of the diagram - and then multiply that by 6 - because cubes have 6 faces.

The area of one face is:

`A_{\text{face}}=3.5^2in^2=12.25in^2`

The surface area of the box is:

`\begin{gathered} S_{}=6A_{\text{face}} \\ S=6\cdot12.25in^2^{} \\ S=73.5in^2 \end{gathered}`
