A pyramid, with a polygonal base and triangular faces, is iconic in ancient monuments (Giza) and modern roofing. Its volume formula (⅓ base area × height) is essential in geometry and civil engineering. The slant height (l) is the height of the triangular face for a regular pyramid. The surface area formula is: Surface Area = base area + ½ × perimeter × slant height. |
