Anthony is laying concrete for a driveway. The driveway is to be 15 feet long by 12 feet wide by 7 inches deep. Answer parts (a) through (c). (a) Determine the volume of concrete needed in cubic feet. The volume of concrete is \( 105 \mathrm{ft}^{3} \). (Simplify your answer. Type an integer or a decimal.) (b) If 1 cubic yard = 27 cubic feet, how many cubic yards of concrete are needed? (Simplify your answer. Type an integer or a decimal. Round to two decimal places as needed.) (

The volume of concrete required for a driveway is crucial because it ensures that the structure is solid and durable. In this case, to calculate the volume, you multiply the length (15 feet), width (12 feet), and depth (7 inches converted to feet, which is approximately 0.583 feet). This results in a total volume of 105 cubic feet. Knowing how to convert cubic feet to cubic yards can save time and prevent ordering more concrete than necessary. Since there are 27 cubic feet in a cubic yard, simply divide the volume in cubic feet by 27. For this driveway, dividing 105 by 27 gives you approximately 3.89 cubic yards of concrete when rounded to two decimal places. That's a little over three and a half cubic yards—perfect for that sturdy driveway!
