Answer:

[tex]n = 6\,rods[/tex]

Step-by-step explanation:

The total of legs needed to build the stools are:

[tex]x = (8) \cdot (3)[/tex]

[tex]x = 24[/tex]

Likewise the total length of the legs is:

[tex]L_{tot} = 24\cdot (0.5\,yd)[/tex]

[tex]L_{tot} = 12\,yd[/tex]

Lastly, the quantity of rods that needed to buy is:

[tex]n = \frac{12\,yd}{2\,\frac{yd}{rod} }[/tex]

[tex]n = 6\,rods[/tex]
