One is 16. 4x4 Another is 18. 3x6 also 36. 12x6 There are quite a few more I am sure but I don't have the time to figure them out.
9x2 . 2x9 . 18x1 . 1x18 . 3x6 . 6x3 all = 18
616 3x6 inch tiles are needed to cover exactly 77 square feet.
The answer will depend on the measurement units used for 3x6.
About 17.

There are about 8 pieces of 3X6 in one square foot (depends on grout lines to some extent). 8 x 15 sq feet would be 120 tiles.
each subway tile is .13 of a sq. foot so you will need 831 pcs. to cover 108 sf.
256 tiles
3 x 6 is 18 square inches. 465 square feet is 66,960 square inches. 66,960 divided by 18 is 3720 tiles. Get 4000 for breakage.
The answer depends on the units of measurement used for the numbers in the question: feet, metres, centimetres, etc. It will also depend on the shape of the area to be covered. A circular shape, for example, will require many tiles to be cut and it will not be possible to use all the offcuts,
Since you didn't say how many tiles there are, you could cover any size floor so long as the area was in multiples of 3x3 or 5x5. So you could have 3x3 or 3x6 or 6x6 etc
