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?

Find the planter’s full volume by multiplying its dimensions: 8 × 18.5 × 7 = 1,036 cubic inches. Halfway full is half that amount: 1,036 ÷ 2 = 518 cubic inches. So the answer is C, 518.0 cubic inches.
