120
The floor area to be tiled is 8 feet by 15 feet, which equals 120 square feet. Since each box covers 16 square feet, you will need 120/16 = 7.5 boxes of tiles. Since you can't buy half a box, round up to 8 boxes for 128 square feet, which will cost 8 * $48 = $384.
10 x 12 = 120
120 cm is equivalent to 3.937 feet.
Assuming that the dimensions given are in feet, the answer is 120 cubic feet ( 15 x 4 x 2 = 120).

A 12x24 tile is 2 square feet. There are 120 tiles that would be needed.
Depends on how much overlap there is with neighboring tiles, and if you need part-tiles at the sides etc. At least 120 at a guess.

120 tiles because the area of the floor is 30 square feet. If you can fit four tiles into one square foot then you could fit 120 tiles in 60 square feet.
A 12 inch by 12 inch tile is 1 ft by 1 ft, which is 1 square foot. So you would need 120 tiles.
First we need to calculate the square footage of the room. 15*20 = 300 square feet Now we need to know how many square feet each tile covers. 20" = 1.667~ square feet 1.6672 = 2.78 square feet. Now we divide the area of the tiles into the area of the room. 300/2.78 = 108 tiles. This gives the exact number of tiles you need mathematically. Realistically you need to account for cutting and breaking. It's safe to round that up to 120 tiles.

The answer depends on the shape of the 30 square feet area. If it is in the form of a strip that is 5 inches wide and 72 feet long and you don't want mosaics with little offcuts, then you will require 144 tiles.
Since it is 16 by 16 inches you must turn 120 ft2 into 17280 in2. Therefore you must find the area of the tiles (256 in2 each) and divide 17280 by 256. You will need 67 1/2 tiles. (I thank the other contributor in recognizing my error)

Assuming all measurements are in the same units, divide 120 / 18 to get the amount of tiles for the width, and 180 / 18 to get the number of tiles for the length. You may need to round up, or down, or break some tiles apart.
