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
