Isn't this a subtraction problem, not a multiplication problem?
If John starts out with 20 fish and lets 6 go, he still has (20-6), or 14, fish.
The formula for the volume of a pyramid is,
V=1/3Bh
Since the base of the pyramid is a square, the base area is 11^2
which equals 121 sq. units
So, substitute 121
for B
and 6 for h, in the formula.
V=1/3(121)(6) = 242 cu. units
Or alternatively 1/3(11^2)(6) = 242 cu. units
