Question

Will someone please help me here

Answer 1

Hey!

You have to divide the total amount she has by the surface area.

Surface area = 2(wl+hl+hw)

That gives you:

`(15 + 18 + 30) * 2 \\ 63 * 2 = 126`

The surface area is 126 ft. Now divide the total amount she has by the surface area.

`1,134 / 126 = 9`

That means she can cover 9 boxes
