Question

Chi has a rectangular window planter that is 8 inches high, 18.5 inches long, and 7 inches wide. If she fills the planter halfway with soil, how many cubic inches of soil are in the planter?

Answer 1

Your answer would be 518 Cubic inches.

18.5 * 7 = 129.5
129.5 * 8 = 1036 (Full planter aka not what we want)
If we take the height and divide it be 2 then we would get 4in (halfway full)
 So 129.5 * 4 = 518 Cu.

I hope I helped!
