A rectangular sheet of metal measures 50cm by 40cm. Equal squares of side x cm are cut from each corner and discarded. The sheet is then folded up to make a tray of depth x cm. What is the domain of possible values of x? Find the value of x which maximizes the capacity of the tray.
I can handle the differentiation part. Just need the equation

I can handle the differentiation part. Just need the equationbecause then the width of the sheet would be zero. Therefore
2. the volume of a prism is calculated by:
The base area is a rectangle which measures (50-2x)(40-2x)
3. Therefore the function of the volume wrt x:
4. Go ahead!
