Step 1
Since 1 inch equals 2.54 cm, multiply the ruler width in inches by 2.54 to convert it to centimeters. The ruler width is 18.0 inches, so the calculation is 18.0 inches * 2.54 cm/inch = 45.72 cm. Record the horizontal surface length as 45.7 cm in Lab Data to 1 Show more…

Measuring lengths of 2 dimensional shapes to calculate area. 1. Obtain two "shape sheets" from your instructor. Each sheet will have an ID code on it. Please record the ID codes on your data sheet. One shape sheet will be a rectangle and the other shape sheet will be a circle. 2. Using a metric ruler, measure the length (l) and width (w) of the rectangle and the diameter (d) of the circle. Record these lengths on your data sheet. 3. Use your measurements to calculate the area and circumference of the circle and to calculate the area and perimeter of the rectangle. Areacircle = ̀πr² Circumferencecircle = 2πr Arearectangle = l x w Perimeterrectangle = 2l + 2w Measuring lengths of 3 dimensional shapes to calculate volume and surface area 1. Obtain a wooden shape from your instructor and record its ID code on the report sheet. 2. Measure the dimensions of the block. If it is a cube or rectangular block, measure its length, width, and height. If it is a cylindrical block, measure its height and diameter of the circular base. If it is a spherical block, measure its circumference. Record the measurements on the report sheet. 3. Use your measurements to calculate the volume and surface area of your block using the formulas given in Table TX.1.
