12 inches = 1 foot Thus the tiles would be 1 foot square. You therefore need 30 to cover a 30 square foot room.
Technically, none. A square foot is a measure of area whereas it is the volume of water that is required. To convert from area to volume it is necessary to know the depth. A twelfth of a cubic foot will cover an area of one square foot to a depth of 1 inch. A cubic foot will cover it to a depth of 1 foot, 100 cubic feet will cover it to a depth of 100 feet.

A square foot is a unit of area. A quart is a unit of volume. The two units are therefore incompatible.
A square foot will cover a square foot, regardless of the depth of the material the cover is made of.

You will need a minimum of 16 square feet of carpet to cover that area.

2.81 gallons for every 1/100 of an inch thick. Most paints are applied at 4 mils wet, so they usually cover about 400 square foot per gallon. So you'd need about a gallon and a quart to cover 450 square feet.
188 will cover it. Bring extra.

A tile measuring 2 foot by two foot (which, incidentally, is an unusually large tile) has an area of 4 square feet, so it would take 100 such tiles to cover a 400 square foot floor.
NONE of these is a metric unit:-- inch, foot, yard, mile-- square inch, square foot, square yard, square mile, acre-- ounce, pound, ton-- fluid ounce, cup, pint, quart, gallon
To cover this area you will need about 10.87 square meters of material.
