30 boxes should work. Ceramic tile normally come in boxes of 10, so you would need 240 tiles or 24 boxes. Then add 20%-30% more for cutting edges, corners, islands, closets, waste, and breakage. That would be 5 - 7 more boxes. But it is best to have a few on hand for future repairs.
The answer will depend on how many tiles per box.
16 square tiles

A square foot is 12" x 12" space. You have 4 ea of 6"x6" tiles in a square foot.
Your answer depends on how many tiles come in each box. All brands of tile are different - your boxes may contain 5, 7, 10, 12, 15, or 18 tiles in each box. Do you mean to say your room is 117 SQUARE feet? If each tile measures 12" x 12" (or one foot by one foot), then each tile is one square foot. With this size of tile, the math is easy. You'd need 117 tiles. Check the labeling on your boxes, and do the math: 117 square feet divided by the number of tiles in each box. The result is the number of boxes you'll need.

400. That's because there are four six-by-six tiles in each square foot. 4 tiles per square foot X 100 square feet = 400 tiles.
The number of concrete tiles in a square depends on the size of the tiles. For example, if you have 12-inch by 12-inch tiles, one square foot (which is 12 inches by 12 inches) would require one tile. If the tiles are smaller, like 6-inch by 6-inch, you would need four tiles to cover one square foot. To determine the exact number, you can divide the area to be covered (in square feet) by the area of one tile (in square feet).
