Answer:
31 1/4 units
Explanation:
The equation for volume of a rectangular prism is length x width x height.
We know the length of the width and height are given as 2 1/2 u.
In this case we can simply find the height by counting the amount of blocks high it is, which in this case is 5.
Then we multiply the numbers together.
2 1/2 x 2 1/2 x 5 = 31 1/4
