Since you didn't include the original numbers for the base area, I just square rooted 9 because there's no other number other than 1 that you would multiply to get 9. Since volume is L*W*H I put 3 for the w and h (because 3*3 is 9) and then I multiplied 9 by 3.5 or 3 and 1/2 (the same thing) to get 31.5. So the volume is 31.5.
