Be careful it's 4 inches not 4 feet.

• math -

(18)(3)(12)(4) = 2592 cubic inches
2592/12 = 216 cubic feet

(You can check if you want, I did it myself so just use a calculator or something)

• math -

3 feet * 18 feet= 54 feet. 4 inches = 1/3 feet....
54 feet* 1/3 feet = 18 cubic feet of concrete!
