Colin is buying dirt to fill a garden bed that is a 9 ft by 16 ft rectangle. If he wants to fill it to a depth of 4 in., how many cubic yards of dirt does he need? If dirt costs $25 per cubic yard, how much will the project cost?
(Note: 1 cubic yard = 27 cubic feet)
The answer I got is $1600. Correct me if I'm wrong.
Answer (2)
3 yd 5 1/3 yd 1/9 yd =1 7/9 yd.^3 =25*2 (I believe they want us to round up) =$50
Colin needs about 1.78 cubic yards of dirt to fill his garden bed, which will cost approximately $44.50. This was calculated by determining the volume in cubic feet and converting it to cubic yards. The correct cost of the dirt is significantly less than $1600.
