A manufacturer is decidiing whether to use a rectangular prism or a cylinder to package three tennis balls with a radius of 3cm. Which package would have less empty space?
Cylinder volume = 32pi * 18 ≈ 508.938
Prism volume = 62 * 18 = 648
The rectangular prism will have a square base of 6 on each side and a height of 18
Its volume is 6^2 * 18 = 648 cm^3
The cylinder will have a radius of 3 and a height of 18
Its volume is pi ( 3^2) * 18 ≈ 508.9 cm^3
The cylinder wastes less space
