Answer:
Step-by-step explanation:
We know that
[tex]1\text{ Feet}=0.33\text{ Yard}[/tex]
[tex]1\text{ Inch}=0.028\text{ Yard}[/tex]
You built one raised garden box that is 12 feet by 6 feet and 10 inches tall.
or you built one raised garden box that is 4 yards by 2 yards and 0.28 yard tall.
Then the volume of the box is,
[tex]=4\times 2\times 0.28=2.24\ yard^3[/tex]
Soil is priced at $5 per cubic yard, so the total cost will be,
[tex]=2.24\times 5=\$11.2[/tex]
