1.182 is correct.
(It has 4 "sig figs" or "significant figures" since the given quantity only had 4 sig figs. Your answer can only be as accurate as the least accurate number given to you. If you would include the digit when you write the value in scientific notation - it's a significant figure. If you wouldn't include it - it's not.)
