Answer:
a is 60 ft^3 and b is 45
Explanation:
b is 45 because 60/4 is 15, which would mean that 4/4 is 60, and since it says 3/4, you subtract 15 from 60 to get 45.
a is 60 because volume equals length times width times height, the three measurements shown
(edit)
and when multiplied you get 60 altogether.
