1. Modelling Your company is going to make its own boxes!

It has been decided the box should hold 0.20m3 (0.20 cubic meters which is equal to 200 litres) of nuts and bolts.

The box should have a square base, and double thickness bottom. Cardboard costs $0.47 per square meter.
It is up to you to decide the most economical shape and size. (Except that the base must be square.)

You must show how you have developed a model to decide the most economical size. In this assignment it is suggested that you follow the following steps

(a) Draw a sketch of your box, and a sketch of a net from which your box can be constructed.

(b) Make a formula for the volume and surface area of your box

(c) Develop a formula for the cost of the box using the area and volume

(d) Draw a graph of the cost of the box using the y-axis as the cost and x-axis as the width of the base.

Remember to include enough information to show us how you drew your graph. Include either the points you plotted, or the formula and drawing package used if you found the graph electronically.

(e) Use the graph to determine the minimum cost, width and height of the box

(f) What are your recommendations for the shape and dimensions of the box?

Note Students who have sufficient background to have other strategies to approach this problem may do so. But they should graph the cost against width to confirm their calculations.

This must be your own work. Any references should be cited in APA referencing format.

The problem is about how to get the optimized value of the dimensions of a box so that the minimum cost of making a box is obtained. In this problem, at first a cost function is obtained, such that it is only dependent on a single variable, the ‘width of the square base’. We obtained an optimum value of ‘width of the square base’, by differentiating ‘cost function’ with respect to ‘width of the square base’ and equating it with zero. From second order differentiation it is confirmed that the value of ‘cost function’ is minimum for the previously obtained value of ‘width of the square base’.Hence, the minimum cost of making the box is obtained along with the dimensions of the box. The paper has been prepared in Microsoft Office Word for Android.
