Answer on Calculus Question for Lauren

Question #1425
You are planning to make an open rectangular box from a 12 by 14 cm piece of cardboard by cutting congruent squares from the corners and folding up the sides.
<br>A) what are the dimensions of the box of largest volume you can make this way? <br>
B) what is the volume?
Expert's answer
Denote the side of the square as x.
The volume of the box would be V = x*(12-2x)*(14-2x) = 4x3 - 52x2 + 168x
Let's find the roots of first derivation dV/dx:
V' = 12x2 - 104x + 168 = 0: x1 = 2 (13-2√37)=1.67 and x2 = 2(13 + 2√37)= 50.33 > 14
Thus the dimentions of the box would be:
{8.66, 10.66, 1.67}.
