How many cubic inches of fluid is forced out of a cylinder by a piston with an area of 20 square inches, when the piston moves five inches?

Explanation:
Volume moved by a piston is found by multiplying the piston’s cross-sectional area by how far the piston travels. With a 20 square inch area and a 5-inch travel, the displaced fluid volume is 20 × 5 = 100 cubic inches. The units line up correctly since square inches times inches give cubic inches. This is why the result is 100 cubic inches. The other numbers come from using only one dimension (area or stroke) or misapplying the distance, such as taking the stroke as the volume or doubling it without a corresponding area change.
