**Luismiguel**, Wednesday, April 18, 2012 at 7:23pmYou have:

lxWxh= volume of a square prism

So...

1.75ft X 5ft X 7ft= 61.25

+17.5( what the kid is missing)

78.75(sum)=(1.75ft)l x W

45=l x W

Proportions:

7ft/35ft=x/45ft= l = 9ft

Then do the same for the width and you get that the final answer is

C. 9ft x 5ft
