List the measurements of three different rectangular prisms that each have a surface area of 20 square units.

So we can use the formula 2lw + 2wh + 2lh, which is the surface area formula and we can set that to equal 20. 2lw + 2wh + 2lh=20

lw+wh+lh = 10

Let's isolate L

Lw+Lh=10-wh

Let's distribute L

L (w+h) = 10-wh

L = (10-wh) / (w+h)

You can use this formula to plug in values for w and h and it will work as long as their products are less than 10
