5 inches, when the real length is 6 inches. Notice how the percentage of error increases as percentage error of 25cm3 pipette the student uses this measurement to compute surface area and accuracy of burette volume. Measurement Compute Surface Area Compute Volume The side of a cube is measured. Measurement: 5 uncertainty of measuring cylinder 100ml in. Actual size: 6 in. Percent of error = Surface area computed with measurement: SA = 25 • 6 = 150 sq. in. Actual surface area: http://www.thestudentroom.co.uk/showthread.php?t=97664 SA = 36 • 6 = 216 sq. in. Percent of error = Volume computed with measurement: V = 5 ³ = 125 cubic in.Actual volume: V = 6 ³ = 216 cubic in. Percent of error = rounded to nearest tenth. 2. A box has the measurements 1.4 http://www.regentsprep.org/regents/math/algebra/am3/LErrorD.htm cm by 8.2 cm by 12.5 cm. Find the percent of error in calculating its volume. ANSWER: Since no other values are given, we will use the greatest possible error based upon the fact that these measurements were taken to the nearest tenth of a centimeter, which will be 0.05 cm. Volume as measured: 1.4 x 8.2 x 12.5 = 143.5 cubic cm Maximum volume (+0.05) : 1.45 x 8.25 x 12.55 = 150.129375 cubic cm Minimum volume (-0.05): 1.35 x 8.15 x 12.45 = 136.981125 cubic cm Possible error in volume: Maximum - measured = 6.629375 cubic cm Measured - minimum = 6.518875 cubic cm Use the "greatest" possible error in volume: 6.629375 cubic cm Remember that percent of error is the relative error times 100%. The percent of error is approximately 5%. Topic Index | Algebra Index | Regents Exam Prep Center Created by Donna Roberts

To measure the percentage error for the amount of liquid that you have gathered using the 25mL graduated cylinder, we can use this formula: percent error measuring cylinder =  maximum error/value of measurement x 100 where: maximum error= is the value written in the apparatus (i.e. `+- 0.1 mL)` *try to look for that value in your graduated cylinder Value of measurement= is the amount of substance that you used, in our case its 10mL  Let's just say that maximum error is equal to `+-.3mL.` `
` ` ` We measuring cylinder uncertainty can have: percent error= 0.30 mL/10 mL  x 100          = 3% error   note: Please provide the maximum error for the apparatus that you are using in order for you to calculate the percent error.  Hope this helps :) like 1 dislike 0 We’ve answered 317,245 questions.
