Answer:
The volume of the cubic yard of concrete will you need to order to fill the mold is:
6.889 cubic yard
Explanation:
It is given that:
The volume of the mold is 186 cubic feet concrete.
Now, it is sold by the cubic yards.
i.e. we have to convert this volume into cubic yards.
We know the conversion that:
![1\ \text{feet}=(1)/(3)\ \text{yard}](https://img.qammunity.org/2020/formulas/mathematics/middle-school/jmriz7as3md2knsgznw1yswkw2aztis7hl.png)
Hence,
![1\ \text{cubic feet}=(1)/(3)* (1)/(3)* (1)/(3) \text{cubic yard}](https://img.qammunity.org/2020/formulas/mathematics/middle-school/972tun39loizso63yd4ujp5i8sfhmlzyal.png)
i.e.
![1\ \text{cubic feet}=(1)/(27)\ \text{cubic yard}](https://img.qammunity.org/2020/formulas/mathematics/middle-school/za6nzpt5850xp22jf28tqxhwc847tp3yz4.png)
Hence,
![186\ \text{cubic feet}=(186)/(27)\ \text{cubic yard}](https://img.qammunity.org/2020/formulas/mathematics/middle-school/waqaxu84inhmmmyaotdg1htsajdfste1i0.png)
![186\ \text{cubic feet}=6.889\ \text{cubic yard}](https://img.qammunity.org/2020/formulas/mathematics/middle-school/7f99xo14se18ytfpp93nv8jyh8f0v7yibk.png)
