Question

Kaylee found the surface area, in square inches of a rectangular prism by using this formula. 2(5 × 3) + 2(5 × 8) + 2(3 × 8) What is the surface area of the prism, in square inches?

Answer 1

2(5 × 3) + 2(5 × 8) + 2(3 × 8) =

= 2(15) + 2(40) + 2(24)

= 30 + 80 + 48

= 158

Answer 2

Surface area of the prism, in square inches is:

158

Explanation:

Kaylee found the surface area, in square inches of a rectangular prism by using the formula:

2(5 × 3) + 2(5 × 8) + 2(3 × 8)

2(5 × 3) + 2(5 × 8) + 2(3 × 8)

= 2(15) + 2(40) + 2(24)

= 30 + 80 + 48

= 158

Hence, surface area of the prism, in square inches is:

158
