I'm doing a lab report and I need help with how of these each are measured. I'll be adding the more information

Procedure: l. Measure the length of the piece of copper wire with the metric ruler. Read the position of both ends ofthe wire. estimating to the nearest tenth of a millimeter. Record both readings in centimeters and read to not run. Make four independent measurementsthat is, use a different pan ofthe ruler for each measurementand record all the readings. Determine the zero reading of the vernier caliper. This is the reading when the jaws of the instrument are in contact with each other. Be sure that the jaws are clean. so no grit or other foreign matter gets between them and prevents true contact. Record the zero reading to [1001 cm make four independent determinations of the readingthat is, open and close the jaws before each settingand record your results. Determine the zero reading of the microme1er caliper, that is, the reading when the surfaces ofthe anvil and the screw end are in contact. Be sure these surfaces are ver},I clean1 since even a small speck ofdust can give a false reading. The screw end may be brought almost into contact with the anvil by turning the ti'Lirnble directly, but actual contact must always be made by taming the ratchet slowly until it clicks several times. Record the value ofthis reading in centimeters and read to {1.0le cm. estimating to one tenth of the smallest scale division. Make four independent determinations of the zero readingthat is1 open and close the instrument before each settingand record the readings. Average the four readings and use them to make your corrections in the next part. Measure the diameter of the copper wire with the tnicromctcr caliper. The measurement is made by placing the wire between the screw end and the anvil and advancing the screw until the wire is gripped between the anvil and screw-end surfaces. Again, the ratchet should be taken not to force the screw. Record the reading in millimeters and read to {ltitll mm. estimating to one tenth of the smallest scale division. Make six independent measurements of the diameter of the wirethat is open and close the caliper before each setting and make the measurement at different points along the wire's length. Also, spin the wire between measurements so that different diameters are measured each time. Record the six readings so obtained. To get the diameter of the wire add or subtract your average zero reading from the sis. measurements you took. 5. Determine the mass of each cube and copper wire using the electric balance
