To calculate the volume of concrete needed, use the formula for volume: length × width × depth. In this case, convert the dimensions to feet: 80 feet long, 40 feet wide, and 0.5 feet deep (6 inches). Therefore, the volume is 80 × 40 × 0.5 = 1,600 cubic feet. You would need 1,600 cubic feet of concrete for the project.
