The length of the box made by Mr. Baker is 10-inch
Mr. Baker has strip of 48- inch long  oak, by this strip he is making the rectangle box of width 14-inch.
<h3>What is a rectangle?</h3>
The rectangle is 4 sided geometric shapes whose opposites are equal in lengths and all angles are about 90°. 
As Mr. Baker has a strip that is 48-inch long and he made a rectangle box with it. 
The width of the  box = 14 inches
now the length of the box = (total length of the strip - 2* width of the box)/2
 ⇒ length of the box = (48 - 2*14)/2
⇒ length of the box = 10 inches  
Thus the Mr. Baker made the box which is 10 inches long.
