First things first. You need to know the formula for finding volume of a pyramid.
The formula is V=1/3Bh or Volume=1/3*Base Area*height
-Remember >Capital B means base area...not base
What did the problem give us?
-The height of the pyramid is 6 cm
-The length and width of the base is 2 cm
Lets plug what we know into the formula.
V=1/3Bh > 1/3(4)6
Now you would have to solve it.
1/3(4)=1.33333333333
1.33333333333*6=8
So the answer is 8 cm.
