PLEASE HELP! What is the volume of the pyramid shown below?
mezya [45]
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
