Question

Samantha is decorating the outside of a box in the shape of a right rectangular prism.The figure below shows a net for the box.

Answer 1

We need to calculate the surface area of a right rectangular prism, for this we can obtain the area of each one of its faces and add them up.

Since the faces are all rectangular, we can obtain their area by using the formula:

`A=lw`

Where l stands for the length and w for the width.

So, we get:

`A_{\text{Total}}=14\cdot15+13\cdot14+15\cdot13+14\cdot13+13\cdot15+14\cdot15`

Therefore,

`A_{\text{Total}}=1174`

So, the answer is A=1174cm^2
