A technician records multiple calibration measurements. The technician uses 3 gage blocks to check the calibrating of the tool they are investigating. They choose a 1 inch gage block, a 2 inch gage block, and a 3 inch gage block.  The technician records the following measurements. For the 1 inch gage block the technician measures 1.000 inches, for the 2 inch gage block the technician measures 2.001 inches, and for the 3 inch gage block the technician measures 2.099 inches. What type of error is most likely present in the measurement

What would the measurement of this feature be?

My son is planning to build a lego plan for a school project and he wants to estimate how much it will weigh. He measured a single lego to weight 12.1 grams. His plan will consist of 100 equally sized legos plus 3 legos that are a quarter of the size for a total of 100.75. He calculates the total mass as 1,219.075 grams. If my son understood significant figures what would his measurement be?
