18" x 18" = 1.5 ft x 1.5 ft = 2.25 sq ft.

Number of tiles required = 700/2.25 = 311.11... so 312 tiles are required.

That is the mathematical answer to the question. In real life, you will need to make an allowance for your skill level and the awkwardness of the shape being tiled - which will affect the proportion of offcuts that can be used.
