CALCULATOR
Rectangular Pyramid Volume Calculator
Find pyramid volume from rectangular base dimensions. Example: Length: 2 m, Width: 2 m, Perpendicular height: 2 m gives 2.66666666667 m³. Rectangular base and apex; height perpendicular to base. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation.
Rectangular base and apex; height perpendicular to base. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation. Derivation: Base area lw times altitude h divided by 3.
Accepted inputs: Length: 0.001 to 1,000 m; Width: 0.001 to 1,000 m; Perpendicular height: 0.001 to 1,000 m.
How the calculation works
V = length × width × perpendicular height /3
Worked example
With length 2 m, width 2 m, perpendicular height 2 m, pyramid volume from rectangular base dimensions is 2.666666667 m³.
Assumptions and limits
Rectangular base and apex; height perpendicular to base. Flat Euclidean geometry; enter stated meter measurements. No material thickness, waste, structural recommendation or curved earth. Display rounding does not change calculation. Derivation: Base area lw times altitude h divided by 3.
