Measurements & Density Instructions Experiment A: Area of a Sheet of Typing Pape

Question

Measurements & Density Instructions Experiment A: Area of a Sheet of Typing Paper Purpose: To determine the area of a sheet of typing paper and express the answer in cm, and in Obtain a sheet of regular typing paper and using the ruler provided measure the length and width of the sheet. The ruler gives readings in two different units, a metric unit in centimeters and an English unit in inches. Make sure that you read the metric scale in your measurements Record your measurements in centimeters rounded to the nearest hundredth of a centimeter Calculate the area (in cm2) of the sheet using the formula: Area # (length)(width) Round your answer to the correct number of significant digits and record it with the correct units Convert the area in cm2 to in? In the Data section, make an appropriate data table (an example data table is shown below) to display all your answers (the initial measurements in centimeters of the dimensions of the paper and the calculated area of the paper in two different units); be sure to include the unit of each number in your table. In the Calculations section, show all your calculations (the area calculation and the unit conversion) clearly. Length Width Areas Typing Paper FEB

Explanation / Answer

The standard dimension of typing paper in most of the country is,

Length = 29.7 cm

Width = 21.0 cm

Area = 29.7 cm x 21.0 cm = 624 cm2 (rounding up to 3 significant figure)

Now 1 cm2 = 0.155 inch2

Hence area in inch2 = 624 x 0.155 = 96.7 inch2
