1. Create an open-top box using a ¼ illustration board. Make sure that you
will be creating the maximum volume of a box.
2. To create a box, you will be removing a square from each corner of the box
and folding up the flaps on each side.
3. Use the concept of problems involving optimization to get the maximum
volume of the box.
4. Explain why you arrive with your final output of creating a maximum vol-
ume of an open-top box.
5. Show your solution on a short bond paper.
Show whether the following equation are exact and hence solve the equation.
a) 2x(ye^x² -1)dx + e^x²dy= 0
b) ( 6x⁵y³ + 4x³y⁵) dx + (2x⁶y² - 5x⁴y⁴) dy =0
A region is bounded by y = square root of x, the x-axis, and x = 4. Write the integral that represents the volume of this region revolved about the line y = 3
