You measured the length, width and thickness of a domino and found its volume. Insert a copy of your data here, along with any previously submitted work you wish to include:
****
The measurement of the domino was 4.9 cm x 2.4 cm x .8 cm.
#$&*
What is the volume of the domino you measured?
****
4.9 cm x 2.4 cm x .8 cm gives us a volume of 9.408 cm^3.
#$&*
What do you find to be the uncertainties in length, width and thickness?
****
The uncertainty seems to be about .5mm for all of these measurements.
#$&*
What therefore are the percent uncertainties in length, width and thickness?
****
The uncertainty for the length is .5mm /(49mm)=.01 or 1%.
The uncertainty for the width is .5mm /(24mm)=.02 or 2%.
The uncertainty for the height is .5mm /(8mm)= .0625 or 6.25%.
#$&*
Which measurement has the greatest percent uncertainty and why?
****
The height has the greatest percent of uncertainty at 6.25%, because it is the shortest of the three measurements used, and the uncertainty was the same, this made the percentage higher than the other two measurements.
#$&*
What is the uncertainty in your calculated volume, based on percent uncertainties in your measurements of length, width and thickness?
****
1%+2%+ 6.25%=9.25%
