Question

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 4in., how many cubic yards of dirt does he need? If dirt costs $25 per yd(cubed), how much will the project cost? (Hint: 1yd(cubed)=27 ft(cubed). The answer i got is $1600. Correct me if in wrong

Answer 1

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
