Sig Fig Help?
1.0m * 5.6cm * 2.1 dm





Convert all measurements to meters.


1.0m * 0.056m * .21m = .01176 cubic meters. Now round to 2 sig figs = .01 cubic meters.





1 cubic meter is equal to 1000 liters


.01176 * 1000 = 11.76 liters. Rounded to 2 sig figs = 12 liters.





1 cubic meter = 61023.7441 cubic inches


.01176 * 61023.7441 = 717.6392, rounded to 2 sig figs = 720 cubic inches.





1 cubic meter = 35.3 cubic feet (rounded)


.01176 * 35.3 = .415128. Rounded to 2 sig figs = .42 cubic feet.
