The volume of a rectanglar prism width 2.5 length 2.5 height 2.5

15.625 units^3

Step-by-step explanation:

The volume of a rectangular prism whose length, width and height are all the same is V = s^3, where x is the length of on edge of the prism.

Here the volume is V = (2.5 units) ^3 = 15.625 units^3

Volume of rectangular prism formula: V = wlh

V = 2.5*2.5*2.5

V = 15.625

Therefore, the volume is 15.625 units^3

Best of Luck!
