Answer:
The volume of prism is length*width*height` V=23*14.2*8=2612.8cm^3
Rounded to the nearest whole number` 2613cm^3.
The volume of cylinder is S*height, where S is the area of circle,
S=Pr^2 -> V=3.14*8*8*23=4624.42cm^3. Rounded to the nearest whole number` 4624cm^3.
The difference between their volume is 4624-2613=2011cm^3.
