Question

Erin's jewelry box is in the shape of a rectangular prism. what is the surface area of Erin's jewelry box?​

Answer 1

190 square inches

Step-by-step explanation

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

`S.A = 2(l * w + l * h + w * h)`

The jewelry box has dimensions

l=10, w=5 and h=3.

We substitute the values into the formula to obtain,

`S.A = 2(10* 5+ 10 * 3 + 5* 3)`

This will give us,

`S.A = 2(50+ 30 + 15)`

`S.A = 2(95) = 190 {in}^(2)`
