Question

a prism is filled with 25 cubes with 1/2 unit side lengths. what is the volume of the prism in cubic units?

Answer 1

the answer is 3.125 i hoped i helped you

Answer 2

Calculate the volume of each of the cube by cubing the length of each edge. 
                                     V = e³
                                     V = (0.5 unit)³ = 0.125 unit cube
Then, we multiply this by 25 in order to get the total volume. That is,
                      total volume = (0.125)(25)
                                         = 3.125 unit cube
