When measurements are multiplied or divided, the answer can contain no more significant figures than the least accurate measurement.

Well I know there is one sigfig, I think whats confusing me is the place holder zeroes in my answer. I am never really sure how many to put in.

jfraser · Answer

your final answer has the correct sigfigs, as @abb0t says. If your original measurement included the decimal point, like 30.m, then there would be 2 sigfigs in that measurement
