Jack has 222 lego cubes, each of side length 1. He puts them together to form a rectangular prism. If the perimeter of the base of the prism is 10, what is the height of the prism?

Your numbers require dimensions. Inches? Centimeters? Meters?

22.2

meter

Perimeter=10, therefore sum of two sides =5.
Try sides 2 and 3, area=6, so height=222/6=37.
Height=37.
