Answer:
611.05
Explanation:
To find the number of cubic feet of water needed to fill Fred's fish tank, we need to calculate the volume of the tank. The volume of a rectangular prism (such as a fish tank) can be found by multiplying the length, width, and height together. Using the given measurements, the volume of Fred's fish tank would be:
8.3 ft * 11.5 ft * 6 ft = 611.05 cubic ft
So, Fred will need 611.05 cubic ft of water to fill his fish tank.
