As of 2014, the cost replaster a pool ranges from $3.22 to $3.68 per square foot. A pool that is 32 by 18 x 10 feet deep equals 1,576 square feet. This would put the minimum cost at $5,075.
96 square feet.

20 ft
Simple ... multiply square feet by cost per square foot.
The square feet is a unit of area, not a unit for mass !!
4,700 square feet at 10.00 per square foot = 47,000
The width of the swimming pool is 10 ft because 10*(10+10)=200
If you are talking about a square yard then it would be 4.20/9=0.47 per square foot. There are 9 feet in a square yard 3 feet wide X 3 feet long = 9 square feet.
