Procedure

Measure and record in Table 1 the length, width, and height in centimeters of a block of wood. Measure to the nearest millimeter, and then estimate to a tenth of a millimeter. The estimated number and all figures to the left of it are significant digits.
Measure the length, width, and height in centimeters of your Laboratory Manual. Record the measurements in Table 1.
Calculate the volume of the block in cubic centimeters. Include only as many significant digits as you have in the value for one dimension of the block. Record the volume in Table 1.
Calculate the volume of the Laboratory Manual in cubic centimeters. Include only as many significant digits as you have in the value for one dimension of the manual. Record the volume in Table
Place the meterstick next to the edge of one page of your Laboratory Manual. Estimate the thickness of one page in millimeters. Record your estimate in Table 2.
Measure the thickness of 50, 75, and 100 pages of your Laboratory Manual in millimeters. Record your results in Table . For each quantity of pages, determine the average thickness of a single page. Record your calculations in the table.

Table 2
Number of pages	Total thickness (mm)	Average thickness of a single page (mm)
1	.	.
50	.	. .
75	.	.
100	.	.

Why is it less accurate to use either end of the meterstick for measuring length?
