Answer:
$933.12
Step-by-step explanation:
This is a composite figure: an upper rectangle and a lower one. We need to find the volumes of each one individually, add the volumes together, then multiply the total volume by .02
The upper rectangle has a volume of:
V = 72×12×24
V = 20,736 cubic inches
The lower rectangle has a volume of:
V = 72×36×10
V = 25,920 cubic inches
The sum of the two volumes is
V = 46,656 inches cubed
Multiply that by .02:
46,656(.02) = $933.12
