To get the volume of a prims, we do the products of the base times its height.
Being a rectangular prims, the area of its base is the product of its dimesions, so the volume of a rectangular prism is simply the product of its three dimensions:
![V=l\cdot w\cdot h=1.3\cdot1.4\cdot c=1.82c](https://img.qammunity.org/2023/formulas/mathematics/college/97at30la0tp47lh2nucuqggocnngvl10eu.png)
Since the volume is equal to 0.728 yd³, we have:
![\begin{gathered} 0.728=1.82c \\ c=(0.728)/(1.82)=0.4 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/o95s4s3meb5emdbb5jjy7n3dyvxiugrpe1.png)
So, the measure of c is 0.4 yards.
