I have to re-roof my garden shed this spring so I thought I'd give ChatGPT a try at calculating the number and cut of sheets required. Not saying I couldn't do it myself but I was interested to see the result.
Question: What's the most economical way to cover an area of 3.2 meters by 2.08 meters with sheets 2.44 metres by 1.22 metres?
ChatGPT Answer:
To cover an area of 3.2 meters by 2.08 meters, you need to determine how many sheets of size 2.44 meters by 1.22 meters you will need.
First, divide the length of the area you need to cover by the length of each sheet to determine how many sheets will fit in that direction:
3.2 meters / 2.44 meters = 1.31 sheets (rounded up to the nearest whole sheet)
Then, divide the width of the area you need to cover by the width of each sheet to determine how many sheets will fit in that direction:
2.08 meters / 1.22 meters = 1.70 sheets (rounded up to the nearest whole sheet)
Since you need to cover the entire area, you will need at least 2 sheets in both directions, which means you will need a total of 4 sheets.
However, since each sheet is larger than the area that needs to be covered, you will have to cut some of the sheets to fit the area. To minimize waste, you can arrange the sheets as follows:

However, since each sheet is larger than the area that needs to be covered, you will have to cut some of the sheets to fit the area. To minimize waste, you can arrange the sheets as follows:
- Place two full sheets in the longer direction, overlapping them by 0.96 meters (the difference between the length of the area to be covered and the length of two full sheets).
- Cut one sheet in half along its width, to create two pieces measuring 1.22 meters by 1.22 meters.
- Place one of these half-sheets in each of the shorter directions, overlapping them by 0.86 meters (the difference between the width of the area to be covered and the width of two full sheets).
