Question

What is the surface area of the box of cookies

Answer 1

We are given a formula for the surface area of a rectangular prism:

`S.A.=2lw+2wh+2lh`

And we are given the dimensions of a box of cookies,

- length 5 in

`l=5`

- width 3 in

`w=3`

height 2 in

`h=2`

And we are asked to find the surface area os the box of cookies. Assuming the box is a rectangular prims, we can simply substitute the dimensions given into the given formual for the surface area:

`\begin{gathered} S.A.=2\cdot5\cdot3+2\cdot3\cdot2+2\cdot5\cdot2 \\ S.A.=30+12+20 \\ S.A.=62 \end{gathered}`

So, the surface area of the box of cookies if 62 in², which corresponds to the fourth alternative.
