What kind of prism? rectangular?

Answer 3

Yes rectangular

Answer 4

lets go with that:
first find the length of the base sides that will add up to numbers that multiply to 50.
if the base was 10x5 this would multiply to 50 and the sides would be 10+5+10+5=30 perimeter.
so now we have all the dimensions of the rectangle. 10x5x7 so add all the area of the 6 sides. (10x5)+(10x5)+(7x10)+(7x10)+(5x7)+(5x7) =?
