Pyramid Calculator

Square pyramid volume, lateral area and slant height

Quick Answer

Pyramid Calculator: Square pyramid volume, lateral area and slant height. Volume V = a²h ÷ 3 (one third of the containing cuboid).

Enter any one value, the rest auto-solve

Base edge a

Height h

Slant height lauto

Step-by-step

斜高 l = √(h² + (a/2)²) = √(12.0000² + 5.0000²) = 13.0000

V = a²h / 3 = 10.0000² × 12.0000 / 3 = 400.0000

侧面积 = 2al = 2 × 10.0000 × 13.0000 = 260.0000

表面积 = 侧面积 + a² = 360.0000，侧棱长 e = √(h² + a²/2) = 13.9284

Formula & How It Works

Square pyramid formulas (base edge a, height h)

Volume V = a²h ÷ 3 (one third of the containing cuboid)

Slant height l = √(h² + (a/2)²)

Lateral area = 2al; total surface = 2al + a²

Lateral edge = √(h² + a²/2)

Example: a=6, h=4 → V=48, slant=5, lateral=60.
