The 9 foot ceiling is simply one more foot in height above the previously stated 8 foot ceiling. One could assume that a man who is 8'7" could only comfortably live under a 9 foot ceiling.

Area of paver = 4 in * 8 in = 4/12 ft * 8/12 ft = 32/144 = 2/9 sq ft Area to be paved = 9 ft * 12 ft = 108 sq ft Number of pavers = Area to be paved/Size of each paver = 108/(2/9) = 486
(6 ft 10 in) + (8 ft 9 in) = (6 + 8) ft + (10 + 9) in = 14 ft 19 in But 19 in = 1 ft 7 in, so (14 ft 19 in) = 15 ft 7 in
The sum of 6 ft 10 inches and 8 ft 9 inches is 15.5833333 feet or 15 feet 7 inches.
44 ft X 9 ft X 8 ft = 3168 ft3 (cubic feet)
To find the cubic volume, multiply the floor space by the ceiling height: 3500 sq ft x 9 ft = 31,500 cubic ft.
I think the standard height of a room is 9 ft
2(9*8 + 9*14 + 8*14) = 620 square feet.

The average ceiling height in a house is typically around 8 to 9 feet.
The typical ceiling height in residential buildings is around 8 to 9 feet.
9 ft x 8 ft=72 ft^2 or 72 sq feet
