CALCULATOR
Square Feet to Cubic Feet Calculator
Find volume from area in square feet and depth in feet. Example: Area: 100 ft², Depth: 2 ft gives 200 ft³. Depth in feet, not inches; use internal measurements for capacity. Flat Euclidean shape; stated measurements in displayed units. No waste, thickness, structural suitability or curved-earth claim. Floating point rounding is display only.
Depth in feet, not inches; use internal measurements for capacity. Flat Euclidean shape; stated measurements in displayed units. No waste, thickness, structural suitability or curved-earth claim. Floating point rounding is display only. Derivation: Area×depth is volume.
Accepted inputs: Area: 0.001 to 100,000,000 ft²; Depth: 0.001 to 1,000 ft.
How the calculation works
cubic feet = square feet × depth feet
Worked example
With area 100 ft², depth 2 ft, volume from area in square feet and depth in feet is 200 ft³.
Assumptions and limits
Depth in feet, not inches; use internal measurements for capacity. Flat Euclidean shape; stated measurements in displayed units. No waste, thickness, structural suitability or curved-earth claim. Floating point rounding is display only. Derivation: Area×depth is volume.
