We have been given that the length of an edge of a square pyramid is 7 and altitude of the pyramid is 12. We are asked to find the volume of the pyramid.
We will use volume of pyramid formula to solve our given problem.
, where,
b = Area of base of pyramid,
h = Height of pyramid.
We know that area of a square is square of its side length, so area of the base of pyramid would be .
The height of the pyramid will be equal to altitude.
Therefore, the volume of the given pyramid would be 196 cubic units and 3rd option is the correct choice.
