Question

Matt plans to put concrete on a rectangular portion of his driveway. The portion is 8 feet long and 4 inches high. The price of concrete is $98 per cubic yard. The total cost of the concrete Matt needs is $58.07. Which of the following is closest to the width of the portion of the driveway on which Matt plans to put concrete?

[1 foot = 12 inches; 1 yard = 3 feet]

0.5 feet
1.5 feet
3 feet
6 feet

Answer 1

The dimensions given are 8 feet length and 4 inches height. The volume of the rectangular portion is $58.07 divided by $98 per cubic yard equal to 0.59255 cubic yards. 8 feet is equal to 8/3 yards and 4 inches is equal to 1/9 yards. Hence the width is equal to 0.59255 cubic yards / (8/3)/(1/9) yards2 equal to 2 yards
