If each triangle is half the size of the rectangle the volume of the triangular-based pyramid will be half the volume of the rectangular-based pyramid or abh6. If the pyramid has a square base this becomes Vdfrac13a2h where a denotes the length of one side of the base. Derive the formula for the volume of a pyramid using calculus. To derive this formula we use the fact that the general formula for volume of a pyramid is V 1 3Bh V 1 3 B h where B is the area of the base and h is the height of the pyramid.
