400 is a significant number because it is a square number as 20*20 = 400
The quantity of 400 m has one significant figure unless specified otherwise. If it is written as 400. or in scientific notation (e.g., 4.00 × 10²), it would indicate three significant figures. Without additional notation, the trailing zeros in 400 are not considered significant. Therefore, it is typically interpreted as having one significant figure.
That depends to what number of figures you are rounding to. Rounded to one significant figure, 361 is approximately equal to 400. Rounded to two significant figures, this is equal to 360.

When multiplying numbers, the result should have the same number of significant figures as the original number with the fewest significant figures. In this case, 400 has one significant figure, and 185 has three significant figures. Therefore, the result of multiplying 400 by 185 will have one significant figure. The answer would be 70,000.
