If you want to cut 24 two-foot braces, how many boards of the length shown below would you need? 12 ft A. 4 B. 6 C. 12 D. 24

Answer 1

We will have that we will need the following number of boards:

We can see that each board can be used to obtain 6 two-foot braces.

So, we will need:

$x=\frac{1\cdot20}{6}\Rightarrow x=\frac{10}{3}\Rightarrow x\approx3.33$

So, we will need 4 boards.
