by hand or by calculator?

You can do it by trial and error. For example, the integer whose square is closest to 53 is 7 as 7 times 7 is 49 but 8 by 8 is 64; therefore, the square root of 53 (call this sqrt(53) for now) must be between 7 & 8.

Since 49 is nearest to 53 than 64, try squaring 7.5. If 7.5 has a square larger than 53 (which it does), try 7.25, etc.
