Answer:
Part (a)
Surface area of a rectangular prism = 2(LW + WH + LH)
Volume of a rectangular prism = L × W × H
where:
- W = width (of base)
- L = length (of base)
- H = height
Given:
- W = 8 ft
- L = 15 ft
- H = 9 ft
Surface area = 2(15 × 8 + 8 × 9 + 15 × 9)
= 2(120 + 72 + 135)
= 2(327)
= 654 ft²
Volume = 15 × 8 × 9
= 120 × 9
= 1080 ft³
Part (b)
Surface Area will help the shed maker know how much metal is needed.
Part (c)
Volume can be used to find out how much the shed holds.
