so volume of rectangular prism=legnth times width times height
width=7
legnth =39 1/2=39.5
height=8
volume=7 times 39.5 times 8=2212 cubic meters=2212m^3 or A
number 2
volume=legnth times width times height
legnth times 8.5
width=3
height=4.5
volume=3 times 8.5 times 4.5=114.75 cubic inces=114.75in^3=C
