Answer:
V = (1/3)(121 in^2)(11 in) = 443.7 in^3
Explanation:
If the side length of the square base is 11 cm, then the area of that base is (11 cm)^2, or 121 cm^2. If the height of the pyramid is 11 cm (as you seem to indicate), then the volume of the squre pyramid is
V = (1/3)(121 in^2)(11 in) = 443.7 in^3
