V= A(h/3) is the formula used for finding square pyramid.
Explanation:
In the above equation V stands for volume , A stands for base area, h stands for height. For finding the volume of square pyramid we need to follow certain steps, they are as follows:
First we need to measure all the side lengths present in the base. Secondly we need to calculate the base area , where the area of one sided square is a*a , then finally we need to multiply the base area with the height of the pyramid . To find the area of the square pyramid we use the formula-
A= a2+2a root over( a2/4+h2 )
