Question

Nathan has three pieces of wood. The first is 9.8 feet in length, the second is 7.5 feet in length, and the third is 12 feet in length. He uses 5.2 feet from the first piece and 6.1 feet from the second piece and does not use the third piece of wood. How many feet of wood does Nathan not use?

Answer 1

First piece:

Nathan doesn´t use= 9.8 ft - 5.2 ft=4.6 ft

Second piece:

Nathan doesn´t use=7.5 ft-6.1 ft=1.4 ft

Third piece:

Nathan doesn´t use= 12 ft.


 feet of wood don´t use=4.6 ft + 1.4 ft + 12 ft=18 ft.


Answer: Nathan doesn´t use 18 feet
