The carpenter's task

Step 1: Imagine that you are a carpenter, who is facing the task of sealing a hole in the floor.

Step 2: But the problem is that the hole in the floor is 120 * 20 cm (each cell = 10 cm), and you only have one sheet of wood plate - 80 * 30 cm.

Step 3: You must seal the hole by making the smallest possible number of cuts.

Step 4: Do you want to learn how to do this? Then look further!

Step 5: Here's how to cut the slab sheet.

Step 6: Next, add the parts as follows.

Step 7: That's it - the hole in the floor is successfully sealed! But we did only one cut!
