There are 12 times 20 = 240 square feet
12' x 20' = 240 square feet
About 7,100 gallons of water.
assuming bases are in feet, 240sq ft
12cm*20cm = 240 cm2 = 37.2 sq inches = 0.258 sq ft
240sq ft
5x8=40sq.inches 12x20=2880. sq. inches divide 2880 divided by 40 = 72 pavers
It depends on whether the depth changes uniformly along the length of the pool.
12X20 = 240 sq feet 12"x12" tiles are 1 sq foot each so must be 240/1= 240
26.67 square yards
assuming that you've measured the room in feet, then square area=Width x Length... so 12ft x 20ft = 240ft2
