1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361, 400, 441, 484
Answer : In total there are 22 numbers.
They are from 11 squared to 22 squared making a total of 12 square numbers between 100 and 500
square numbers between 1 and 500 There are 22 square numbers between 1 and 500 here they are 1, 4,9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361, 400, 441, 484.
There are infinitely many such numbers.
1000
500 (square feet) = 46.45152 square meters.
500 x 9 = 4500 square feet
500 acres = 0.78125 square miles
500 acres = 0.781 square miles.
There are 144 square inches in a square foot - so there are 72,000 in 500 square feet.
1500 square meters are 16145.865625 square feet.
The question does not make sense. There are not 500 prime numbers but infinitely many!
