Three measurements need to be known to compute the volume of any box with a rectangular shape. Multiply this number by 2. Solution to Problem 1.
Optimization Problem 5 -.
As V lbh V l A2- lblh from equation ii V lA2 l 2 bh V lA2 l 2 P4-l from equation i V lA2 l 2 P4 l 3 - iii Now differentiate V wrt l for finding maximum of volume. We first use the formula of the volume of a rectangular box. Lets make it dependent on only length. So if we cut X inches from our rectangle.
