36 inch board = 3 ft.
72 inch board = 6 ft
144 inch board = 12 ft.
First, let us solve how many feet long a 36 inch board would be:

18 inches = 11/2 feet
36 inches     x feet

x= 11/2 x 36 ÷ 18
x= 11

Therefore, a 36-inch board would be 11 feet long.

Next question!

18 inches = 11/2 feet
72 inches     x feet

x= 11/2 x 72 ÷ 18
x= 22

Therefore, a 72-inch board would be 22 feet long.

Last question!

18 inches = 11/2 feet
144 inches     x feet

x= 11/2 feet x 144 inches ÷ 18 inches
x= 44

Therefore, a 144-inch board would be 44 feet long.

Hope this helps!
