Set it on the table so that it is a circle looking down at it.

Cut straight down, all the way, along a diameter.
Turn 90 degrees and cut straight down along a diameter perpendicular to the first cut.
Now make a horizontal cut through all four pieces halfway up the cylinder.

To slice a cylindrical piece of cheese into eight congruent pieces with three slices, follow these steps:

Step 1: Start by placing the cylindrical piece of cheese on a flat surface, such as a cutting board or a plate.

Step 2: Take the first slice and cut it horizontally through the middle of the cylindrical piece of cheese. This will divide the cheese into two equal halves.

Step 3: Take the second slice and cut it diagonally from one side of the cylindrical piece of cheese to the other. The angle of the slice should be such that it divides the cheese into four equal pieces. This means that the slice should intersect with the first slice at a right angle (90 degrees).

Step 4: Finally, take the third slice and cut it diagonally from the other side of the cylindrical piece of cheese to the other, forming an "X" shape with the second slice. Again, make sure the angle of the slice is such that it divides the cheese into four equal pieces, intersecting with the other slices at right angles.

By following these steps, you will have sliced the cylindrical piece of cheese into eight congruent pieces with three slices. Each piece will be of equal size and shape.
