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

viktelen [127]

ANSWER

190 square inches

EXPLANATION

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

$S.A = 2(l \times w + l \times h + w \times h)$

The jewelry box has dimensions

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

We substitute the values into the formula to obtain,

$S.A = 2(10\times 5+ 10 \times 3 + 5\times 3)$

This will give us,

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

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