Answer:

Step-by-step explanation:

20in * 20in = 400in sq

400in sq * 5 sides = 2,000in sq needed.

4in * 4in = 16in sq

Take the 2,000in sq needed and divid it by the 16in each tile covers.

2,000 / 16 = 125 tiles

Therefore, you would need 125 tiles to cover 5 sides of the table.  Top and four sides.
