Dana helped

Dana helped her dad build a sandbox for her younger sister. The sandbox is shaped like a rectangular prism that is 4 1/2 feet long and 4 feet wide. Dana used bags of sand to fill the sandbox 1/2 of a foot deep. Each bag contained 1/2 of a cubic foot of sand. How many bag must she buy?

Correct answer:

n =  14

Step-by-step explanation:

a=412=4+12=4 2+12=92=4.5 ft b=3 ft c=12=0.5 ft V1=12=0.5 ft3  V=a b c=4.5 3 0.5=274=634=6.75 ft3  n1=V/V1=6.75/0.5=272=1312=13.5  n=n1=13.5=14
