4. You are constructing a rectangular storage shed with a square base. You need space to accomodate 75 m of stuff. The floor is made of concrete which costs 2$/m². The four walls are made of wood, which costs 5 $/m². The roof tiles cost 4 $/m2 (a) Write a formula for the total cost of the shed in terms of a single variable. Indicate what this variable represents, and state its domain. (3 marks) (b) What should be the dimensions of the shed to minimize the cost? State the length, width and height, and also the minimum value of the cost. (5 marks) (c) Suppose you only have enough concrete to cover an area of 16 m². How does this change the domain of the variable you chose in part (a)? (1 mark) (d) With the restriction from part (c), can you achieve the minimum cost you

In a beehive, each cell is a regular hexagonal prism, open at one end with a trihedral angle at the other end as in the figure. It is believed that bees form their cells in such a way as to minimize the surface area for a given side length and height, thus using the least amount of wax in cell construction. Examination of these cells has shown that the measure of the apex angle is amazingly consistent. Based on the geometry of the cell, it can be shown that the surface area S is given by

where s, the length of the sides of the hexagon, and h, the height, are constants.
