Question

I need help with 7, 8, 9,10 I don't understand how to do this.

Answer 1

We have that the formula for the volume of a rectangular prism is:

`V=l\cdot w\cdot h`

where 'l' is the length, 'w' is the width and 'h' is the height.

In this case, we have the following:

`\begin{gathered} l=2yd \\ w=1(2)/(3)=(5)/(3)yd \\ h=5(1)/(3)=(16)/(3)yd \end{gathered}`

then, using the formula, we get:

`V=2\cdot(5)/(3)\cdot(16)/(3)=(2\cdot5\cdot16)/(3\cdot3)=(160)/(9)=17(7)/(9)yd^3`

therefore, the volume is 17 7/9 yd^3
