Another 53.75 square feet of tile would be needed.
1 square yard = 9 square feet so 195 sq feet = 195/9 sq yards = 21.66... sq yards.

To determine how much gravel is needed to fill an area of 10 by 5 feet, you first calculate the area by multiplying the length and width: 10 feet × 5 feet = 50 square feet. Next, decide on the desired depth of the gravel fill (for example, 3 inches or 0.25 feet). Multiply the area by the depth to find the volume in cubic feet: 50 square feet × 0.25 feet = 12.5 cubic feet of gravel required.
Almost exactly 2 x 2 ft2
It depends on how high you would like to fill it. You see, a liter is a 3-dimensional measure of volume (like a cubic foot is), and a square foot is a 2-dimensional measure of area. So, for example, to fill an area of 10,500 square feet to a height of 1 foot, you would need 297,326.889 liters.
Just multiply 1/2 foot x 12,000 square feet. The answer will be in cubic feet.
