What is the volume of the prism? enter your answer in the box as a mixed number in simplest form it has a height of 1 1/2 a length of 2 1/2 and a width of 3 1/2

The volume would be length x width x height:

1 1/2 x 2 1/2 x 3 1/2 

 1 1/2 = 3/2
2 1/2 = 5/2
3 1/2 = 7/2

3/2 x 5/2 x 7/2
multiply the three top numbers and then the 3 bottom numbers:
 3*5*7 = 105
 2*2*2 = 8 

so the answer is 105/8, now simplify to get 13 1/8 cubic units
