Describe the dimensions of two different prisms that each have a volume is 2,400 cubic centimeters
Phantasy [73]
One prism with a volume of 2400 might have a rectangular base with a length of 4 and a width of 5, as well as a height of 120. 

V = l x w x h
V = 4  x 5 x 120
V = 2400

This prism would essentially look like a really tall rectangle, since the height is such a large number. I wouldn't accurately represent the units on graph paper, if I were you. Just label the sides with the numbers I gave you.

Another prism with a volume of 2400 might be a rectangular prism with a length of 8, a width of 10, and a height of 30. 

V = l x w x h
V= 8 x 10 x 30
V = 2400

This would also be a tall rectangle, although it isn't as tall. Keep in mind that l x w x h is only the volume formula for a rectangular prism. I only used rectangular prisms because they would be the easiest for this example. A triangular prism has a different volume formula.
