The answer is 27 cubic meters. Why? Well, the formula for the volume of a rectangular box is length times width times height (or base times height because length and width make up what is known as the base). Provided these measurements, all we need to do in this equation is multiply the length, width, and height to get our volume.
1.8 x 1.2 = 2.16
2.16 x 12.5 = 27
Because we just multiplied all three numbers by each other, we have identified our missing volume. The volume of the rectangular box is 27 cubic meters.
Your final answer: A.
