Answer:
- volume: 600 cubic inches
- area: 500 square inches
Explanation:
You want the volume and surface area of a rectangular crate that is 15 in long, 4 in wide, and 10 in high.
Volume
The volume is given by the formula ...
V = LWH
For the given crate, the volume is ...
V = (15 in)(4 in)(10 in) = 600 in³
Area
The area is given by the formula ...
A = 2(LW +H(L +W))
For the given dimensions, the crate has an area of ...
A = 2((15 in)(4 in) +(10 in)(15 in +4 in)) = 2(60 in² +(10 in)(19 in))
= 2(60 in² +190 in²) = 500 in²
The crate's volume is 600 cubic inches; its area is 500 square inches.
