Answer:
13.125 in³
Step-by-step explanation:
So first convert all the numbers to decimal form. 3/2 converts to 1.5. 7/2 converts to 3.5. 5/2 converts to 2.5.
Now for the actual math. Take 1.5×3.5=5.25. Then take your new number and multiply it by 2.5. 5.25×2.5=13.125.
D because a rational number can be converted into a fraction and the square root of 5 cannot be covert into a fraction because it equals 2.2
