A square wall tile has an area of 58,800 square millimeters. Between which two measurements is the length of one side?

Answer 1

58,800 square millimeters

5 88 00 [Write two numbers at a time starting from the right.]

Here is a handy table:

number ... square root

1 00 00 .. 100 mm = 1 cm

4 00 00 .. 200 mm = 2 cm

9 00 00 .. 300 mm = 3 cm

If the ruler shows centimeters, a side is between 2 and 3 cm

If exactness is expected, SQRT(588000) = 242.4871 mm which

is between 24 cm 2 mm and 24 cm 3 mm.
