Assume you repeated measurements of sides a, b and c five times with the instrument(s) of your choice and got exactly the same values for each side, or aave = 1 cm have = 1 cm cave = 50 cm What are the absolute and relative uncertainties of the measurements for each side? I know you have to convert mm and m to cm, but i am still not understanding.

2. Suppose you are given a block with sides a xbxc=1 cm x 1 cm x 50 cm, Initially you do not
know that the block measures 1 cm x 1 cm x 50 cm. You have a meter stick and a micrometer.
The smallest division of the meter stick is Imm and the smallest division of the micrometer is
0.01 mm. The micrometer can measure up to 10 cm while the meter stick can measure up to 1 mn,
a. Which instrument(s) will you use for measuring the volume of the block? Why?
b. Assume you repeated measurements of sides a, b and e five times with the
instrument(s) of your choice and got exactly the same values for each side, or
dave1 cm
