What is the uncertainty at 95% (in cubic feet) of the same rectangular excavation from previous question? the dimensions are repeated as follows: length = 299.150+/-0.805 feet width = 99.100+/-0.650 feet depth = 22.000+/-0.700 feet note: your answer should be rounded based on the rules of the significant figures (of the errors). only make rounding after the final answer is computed. do not include unit in the answer.
