Measure the length of the room in feet (12 inch increments) and then the width of the room in feet (12 inch increments). Next multiply the length by the width and you will have the square footage. If your room is an odd shape then break it down into quadrilateral shapes (squares and rectangles) measure length and width of each, multiply, and add the totals together for total square footage of a room.

It is: 280*19 = 5320 cubic feet
9ft times 3ft is 27 sq. ft. 9ft times 10ft is 90 sq. ft. 9ft times 0.5ft is 4.5 sq. ft. This adds up to 121.5 sq. ft. Therefore 13.5 ft. (multiplied by) 9 ft. is 121.5 sq. ft.

In the extremely unlikely event that the room has no doors (nor windows), Area of floor and ceiling = 99 sq ft each. Area of smaller walls = 72 sq ft each. Area of larger walls = 88 sq ft each.
300 sq ft X 144 sq in/sq ft = 43200 sq in 43200 sq in /(16 in X 16 in) = 169 tiles That is true if the tiles fit exactly. If you have to cut some tiles because the length or width of the floor is not an exact multiple of 16 inches, then you may need more.
