- For these questions, be sure to apply the rules for significant figures. a You are conducting an experiment where you need the volume of a box; you take the length, height, and width measurements and then multiply the values together to find the volume. You report the volume of the box as 0.310 m1. If two of your measurements were 0.7120 m and 0.52145 m, what was the other measurement? b If you were to add the two measurements from the first part of the problem to a third length measurement with the reported result of 1.509 m, what was the value of the third measurement?arrow_forwardThe label on a bale of mulch indicates a volume of 1.45 ft3. The label also states that the mulch in the bale will cover an area of a garden 6 ft 6 ft to a depth of 1 in. Account for the discrepancy in the given volumes.arrow_forwardWhat is the difference in surface area between two circles, one of radius 7.98 cm, the other of radius 8.50 cm? The surface area of a circle of radius r is r2. Obtain the result to the correct number of significant figures.arrow_forward
- When you perform the following operations, how many significant figures should your answer have? Assume these are measured quantities. 312.3415 + 0.0100 = 07 8. 1 3 6.arrow_forwardA student completed Part C using a small sheet of aluminum metal (?=2.70 g/cm3). The sheet had a mass of 1.3648 g, a length of 2.05 cm, and a width of 2.20 cm. Calculate the thickness of the aluminum sheet in units of millimeters. Report only the numerical portion of your answer (and watch your significant figures!)arrow_forwardMass (g) Height (cm) Diameter (cm) Cylinder A 15.560 5.11 1.20 Cylinder B 35.536 5.90 1.30 In your calculation use the value 3.14 for π. Write your answer to the correct number of significant figures. Calculate the volume of Cylinder A and B using the dimensions of the cylinder.arrow_forward
- Five silver coins are added to 454.0 mL of water. The water level rises to a volume of 545.0 mL. What is the volume of the five silver coins? Express your answer with the correct number of significant figures. Write your final answer in the space below. Don't forget to show your calculations for your answer at the end of this quiz. Please include the question number with your calculations so I know which question they are for.arrow_forwardDo the following multiplication and division calculations. Give a final answer with the correct number of significant figures and the correct units. Units can cancel or multiply just like number factors. (2.5 x 103 m/s) x (5.00 x 10-6 s) = ?arrow_forwardPerform the following calculation. Round your answer according to the correct number of significant figures: Write your final answer on the blank. 234.97 x 2.98 =arrow_forward
- 6. What is the mass, in g, of a piece of iron that has a volume of 1.50 x 10² and a density of 7.20 g/mL?arrow_forward8. Your calculator gives you the number 1761.2868 as the volume (in cm^ 3) of a box 2.0 ft by 6.5 cm by 1.75 în. Since this number should reflect the precision of the physical measurements, how many significant figures will you record for the volume of the box? What is the volume of the box?arrow_forward3. When a piece of metal weighing 108 g is submerged in water the volume changes from 36.9 mL to 49.2 mL. Calculate the density of this metal. 4. The accepted value for the density of a certain metal is 6.81 g/cm³ . Calculate the percent error in a laboratory measurement that gives a density value of 6.6 g/cm³ . Express this result in the proper number of significant figures.arrow_forward
