I dont really have a answer i just wanted to say that this fish box thing is the same of what i have on my test the SAME pic Lol just wanted to point that out :/
To find the volume of each prism, you will multiply the length by the width by the height.
V = lwh 3 3/4 x 3 x 3 1/4 V = 36 9/16 cubic feet
V = lwh 1/4 x 1/4 x 1/4 V= 1/64 cubic feet
Both boxes are similar in that they can be described as a rectangular prism.
They are different because one prism has congruent edges, so we call it a cube. The other one has varying side lengths, therefore it is only a rectangular prism.
