Final answer:
To calculate the concrete needed for a driveway section 10 ft long, 8 ft wide, and 1/2 ft thick, multiply these dimensions to find the volume, which is 40 cubic feet of concrete.
Step-by-step explanation:
To calculate the number of cubic feet of concrete needed for a driveway section that is 10 ft long, 8 feet wide, and 1/2 foot thick, you would use the formula for the volume of a rectangular prism, which is length × width × height. Follow these steps:
Multiply the length (10 ft) by the width (8 ft) to find the base area, which is 10 ft × 8 ft = 80 ft².
Multiply the base area by the thickness (0.5 ft) to find the volume, which is 80 ft² × 0.5 ft = 40 cubic feet.
Therefore, you would need 40 cubic feet of concrete for the driveway section.
