Each of thesethree pieces should be 3ş feet long. He needs to buy two pieces for the sides. These twopieces should be 4-— feet each. Finally, he will need to buy one piece for the top. This pieceshould be 4 feet. What is the total length of wood that Fran needs to buy?

Answer 1

Let's rewrite the mixed number as a fractions:

$\begin{gathered} 3\frac{2}{3}=\frac{11}{3} \\ 4\frac{1}{2}=\frac{9}{2} \end{gathered}$

Therefore, the total length will be:

$3\cdot(\frac{11}{3})+2(\frac{9}{2})+4=24ft$
