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.

You don't have the graph icon here, so we'll have to graph this parabola without it.
Your parabola is y = -x^2 + 3., which resembles y = a(x-h)^2 + k. We can tell immediately that this parabola opens down and that the vertex is (0,3).
Plot (0,3). Besides being the vertex, this point is also the max. of the function.
Now calculate four more points. Choose four arbitrary x-values, such as {-2, 1, 4, 5} and find the y value for each one. Plot the resulting four points. Draw a smooth curve thru them, remembering (again) that the vertex is at (0,3) and that the parabola opens down.
 
        
             
        
        
        
Your answer is 199cm is not equal because of 10mm equal 1cm and 100cm equal 1 meter and 100,000cm equal 1 km. Hope this helps.
