A 1-yard distance is equivalent to 3 feet. If a driveway is 15 yards long, simply multiply 15 by 3 to find the number of feet. The length of a 15-driveway would be 45 feet.
The conversion between square yards and square feet also uses basic multiplication. For example, if a flower bed is 10 square yards, multiply 10 by 3 by 3 to equal 90. Ten square yards is equal to 90 square feet.
A cubic yard contains 27 cubic feet because the cubic yard measures volume and not just area or linear length.
