Enter base edge and height, then press Calculate.
Square pyramid formulas
Base area: A_base = s²
Slant height: l = √(h² + (s/2)²)
Lateral surface area: A_lat = 2 · s · l
Total surface area: A_total = s² + 2sl
Volume: V = (1/3) · s² · h

Frequently asked questions
This calculator handles right square pyramids — pyramids with a square base whose apex is directly above the center of the base.
Any pyramid has exactly one-third the volume of a prism with the same base and height. This is true for any shape of base — square, triangular, or general polygon.
