Question

Janice makes a box in the shape of the rectangular prism. Show your work and explain how you solved using first, next & last. What is the surface area of the box

Answer 1

The surface area is
`376in^2`

Explanation:

The surface area of a rectangular prism is calculated using the formula;

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

The length of the rectangular prism is
`l=10in`

The height is
`h=6in`

The width is
`w=8in`

The surface area

`S.A=2[10(8)+10(6)+8(6)]`

`S.A=2[80+60+48]`

`S.A=2(188)`

`S.A=376in^2`
