Square Pyramid Volume Calculator
Calculate volume, surface area, and slant height of a square-based pyramid.
About this calculator
The Square Pyramid Volume Calculator on NumberCals is a free, mobile-friendly tool for anyone needing to calculate volume, surface area, and slant height of a square-based pyramid. Enter your values in the form below and the result is computed instantly — no sign-up, no installation, no waiting.
Formula used
V = (1/3)·b²·h; SA = b² + 2·b·ℓ; ℓ = √(h² + (b/2)²)
What you'll need
- Base Side Length (e.g. 6)
- Perpendicular Height (e.g. 8)
What you'll get
- Volume
- Slant Height (face)
- Total Surface Area
Formula
V = (1/3)·b²·h; SA = b² + 2·b·ℓ; ℓ = √(h² + (b/2)²)
