This is an incorrect question, the correct question is given below.

Martin is building a model. He cuts two pieces of wood that are each $6\frac{1}{3}$ inches long from a board with a total length of 18 inches. What is the length, in inches, of the remaining part of the board?

Answer : The length of the remaining part of the board is $5\frac{1}{3}$ inches.

Step-by-step explanation :

As we are given that:

Total length of the board = 18 inches

Length of each piece of wood cut from the board = $6\frac{1}{3}$ inches = $\frac{19}{3}$ inches

Length of 2 pieces of wood cut from the board = $2\times \frac{19}{3}$ inches

= $\frac{38}{3}$ inches

Length of the remaining part of the board = Total length of the board - Length of 2 pieces of wood cut from the board

Length of the remaining part of the board = $18-\frac{38}{3}$ inches

= $\frac{54-38}{3}$ inches

= $\frac{16}{3}$ inches

= $5\frac{1}{3}$ inches

Therefore, the length of the remaining part of the board is $5\frac{1}{3}$ inches.
