How much paper would you need to cover this
prism?

Nice background XD
Alright, jokes aside, if you know me, you'd know, answer is at the bottom, explanation is right here, alright, lets get into it.
I automatically cancel out 14^2 and 117.5^2 for being too high and too low numbers. 58.75 is way to off of a number added on to the fact that theres 1 whole number and 2 half numbers, I ruled everything out except 75^3 so I did the math and I was correct, it was 75 in^3!
Alright, have a good day!
