The volume of a pyramid with a square base is given by the formula, V = 1/3 L^2H, where L = length of the side of the base and H = height of the pyramid. 

a) Solve the formula for height, H.

b) Use the new version of the formula to find the height if the volume of the pyramid is 168 cubic meters and its base length is 6 meters.

I believe H=14 but i'm not sure.
