5 MODEL#3: Understanding How SFs Propagate in Calculations. C. 4.0000 cm² 136.8 mm C. 3800. g f. 1.70×104 g/cm³ a. Calculate the volume (length x width x height) in units of mm³ (mm × mm x mm) for the large eraser shown below. Report your answer to as many digits as your calculator displays. 254.7 mm fufc 25.3 mm Jef b. Estimated uncertainties in measurements are at least ±1 value in last reported digit. Estimate the new volume if each of the above measurements were 0.1 mm larger (136.9 mm x 254.8 mm x 25.4 mm). 2 c. Starting from the left, which digit is the 1st digit in the answers from a & b that differ? If you report all the values that agree plus the 1st value where the answers disagree, how many SFs should you report?

I need accurate answer with full detail. This is my only chance to get it right.
