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.

Significant figures are important for science, they tell how certain you are of a certain value. The rules for significant figures are as follows: If it is a decimal number, look at the first number on the left. If it is not zero, start counting the amount of numbers, and that's how many significant figures you have. For example, 7.495 has 4 significant figures. If it is zero, keep going until there is digit larger than zero, and start counting the numbers until the end. However many numbers there are, that's how many significant figures you have. For example, 0.000331 has 3 significant figures. If the number does not have a decimal, start from the right and if the number is not zero, start counting numbers and that's how many significant figures you have. For example, 93847 has 5 significant figures. If it is zero, the first significant figure will be the first non-zero digit. For example 3873000 has 4 significant figures. When you add or subtract some numbers, the amount of significant figures the answer should be expressed in depends on the number with the least amount of decimal places. For example, 4.398 + 5.2 = 9.6 You express the answer to the lowest number of decimal places a value you are adding or subtracting has. When you multiply or divide numbers, the answer is expressed to the lowest amount of significant figures that the values have. For example: 55 x 7 = 400 (when expressed with correct significant figures)

400 is a significant number because it is a square number as 20*20 = 400

both 40 and 400 have one because there is no "." the 0.7000 has four SF because you know that the first three digits after the seven are exact while the last zero could be rounded. the concept is a little tough to get but once you do its pretty simple.

dont worry, i have just research more and have found the answer. there are 400 figures :)

1. All non-zero numbers are significant 2. Zeros between non-zero digits count 3. Zeros at the beginning of a number do not count 4. Zeros at the end of a number that does not have a decimal are not significant 5. Zeros at the end of a number with a decimal are significant

0.500 liters one half a liter (accurate to three significant figures)
