The volume of a pyramid is given by the formula:
V = (1/3) * base area * height
Since the Great Pyramid is a square pyramid, its base is a square with edge length of 230 m. Therefore, its base area is:
base area = 230^2 = 52,900 square meters
And its height is 147 m.
So, the original volume of the Great Pyramid was:
V = (1/3) * 52,900 * 147
= 2,592,100 cubic meters
Therefore, the original volume of the Great Pyramid was 2,592,100 cubic meters.
