Materials Needed: The box from the last experiment; a ruler that measures centimeters. Procedure: Measure each side of the box in centimeters. Use the formula for the volume of a box shaped object (V = L x W x H ) to calculate the volume of this box in cubic centimeters. What Happened: Each side was 10 cm long. When you plug the numbers into the formula and do the math, you get:
