Length of wood Samuel needs to build a fence = 346 feet
Length of each piece of wood = 15 feet
Number of wood pieces he will have with him :-
![= (346)/(15)](https://img.qammunity.org/2021/formulas/mathematics/college/4tud14gkxntiejqkhsmd0yu186cm4t5pxk.png)
Samuel will need 23 pieces of wood .
Length of wood Theresa needs to build a fence :-
= 346 × 2
= 692 feet wood
Number of wood pieces Theresa will need :-
![=(692)/(15)](https://img.qammunity.org/2021/formulas/mathematics/college/a6zf1gz4cgw6j34rxqorxt641f1xpmppne.png)
![= 42 \: pieces \: of \: wood](https://img.qammunity.org/2021/formulas/mathematics/college/3kxncakj3jzpt8c5hzes4fpl097m1j01se.png)
Therefore , Samuel needs 23 pieces of wood and Theresa needs 42 pieces of wood .
