Recently I have encountered a problem in which I was to figure out how many seconds I was in class each week. My class is 0.833 hours long and we meet three times a week. I came up with 8,996.4 seconds. I need to round this to three significant figures because there are 3 in the information provided in the question (correct?) but everything rounds up and I would have 9,000...which is not 3 significant figures. Help please?
