Question

Today, I am making a triangle-shaped sandbox for my sweet, little Maci. Papa gave me 30' in length of 2"x 4' planks. I would like the longest side to be 12'. What is one possible combination for the other two sides? (show work)

Answer 1

If you have 30' in 2x4 planks and you want the longest side to be 12', subtract 12' from 30' to determine how many feet of planks you have left:

30' - 12' = 18'. You could divide this 18' by 2 and by doing so get two 9' planks for the (equal) shorter sides of your triangular box.
