6th grade math - volume and area of a prism

[superp]

Here is the question:

a rectangular prism has dimensions 3in, 4in and 5in. Find another rectangle prism with the same volume but less surface area

Obv the volume is 60, but cannot figure out 2nd part of question. HELP!​

What's the surface area?

I'd try a cube, first, then maybe a circular cyllinder.

First try different 3 number combinations that give you the volume of 60.....like 3*2*10=60 (unfortunately the surface area is 112 for that combo)
I have feeling you are going to have to use numbers that are decimals inorder to get the lower surface area.

Good luck!
