Measure the length, width, and height of the object or space in feet
Multiply length × width × height
Use the formula: cubic feet = L × W × H
Convert inches to feet before calculating if needed
Divide inches by 12 to get feet
Convert measurements in yards or meters to feet if needed
For irregular shapes, break the space into smaller rectangular sections
Calculate the cubic feet of each section separately
Add the results together
Use a measuring tape for accurate dimensions
Round measurements only after calculating if possible
