Pyramid Volume and Surface Area
V = (1/3)*base area*height for any base shape. Square: base=s^2. Equilateral triangle: base=(sqrt(3)/4)*s^2.
Slant height = distance from apex to midpoint of base edge. For square: sqrt(h^2+(s/2)^2).
The Great Pyramid has 230.4m base and 146.5m height, volume about 2.6 million cubic meters.
Frequently Asked Questions
Pyramid volume?
V = (1/3)*base area*height. Works for any base shape. One-third of equivalent prism.
Slant height?
sqrt(height^2 + apothem^2). Apothem = distance from center to midpoint of base side.
Surface area?
Total = base area + lateral area. Lateral = (1/2)*perimeter*slant height for regular pyramids.
Is tetrahedron a pyramid?
Yes, with triangular base. Regular tetrahedron has all equilateral triangle faces.
