A three dimensional object has length, width, and height. This investigation will give you practice finding volume for different solid objects. Materials • Pencil • Calculator Calculating volume of a cube A cube is a geometric solid that has length, width and height. If you measure the sides of a cube, you will find that all the edges have the same measurement. The volume of a cube is found by multiplying the length times width times height.
Procedure: Part I: Rectangular Solid (Wooden Block) Mass: In order to find the mass of the rectangular solid utilize the balance.Document the mass by rounding to the closest 0.1 g in the data table underneath. Volume: Find out the length, width, and height of the rectangular solid by utilizing the metric ruler. Document these by rounding to the closest 0.01 cm. Utilize the formula for
Part C: Density of an Irregular Shaped Solid 1) Obtain a sample of metal and determine the mass. 2) Fill a 100 mL or 50 mL graduated cylinder with water, recording its volume. 3) Using the water displacement method, determine the volume of the object. 4) Determine the density and percent error. Part D: Density of Methanol 1) Find the mass of an empty 10 mL graduated cylinder, and then fill approximately 9 mL of methanol and record volume.
Name: ______________________ Date: ________________________ Student Exploration: Density Laboratory Vocabulary: buoyancy, density, graduated cylinder, mass, matter, scale, volume Prior Knowledge Questions (Do these BEFORE using the Gizmo.) Of the objects below, circle the ones you think would float in water. Why do some objects float, while others sink? ____________________________________ _________________________________________________________________________ _________________________________________________________________________ Gizmo Warm-up The Density Laboratory Gizmo™ allows you to measure a variety of objects, then drop them in water (or other liquid) to see if they sink or float. An object’s mass is the amount of matter it contains.
Name: ______________________ Class: _________________ Date: _________ ID: A quiz 6.1-6.3 Multiple Choice Identify the letter of the choice that best completes the statement or answers the question. ____ ____ 1. Determine which binomial is a factor of −2x 3 + 14x 2 − 24x + 20. a. x + 5 b. x + 20 c. x – 24 d. x – 5 2. The volume of a shipping box in cubic feet can be expressed as the polynomial 2x 3 + 11x 2 + 17x + 6. Each dimension of the box can be expressed as a linear expression with integer coefficients.
5 .For part III, Average was needed to be found after Find the Mass/A of each all 5 disk. To do that Add all the values in Table 3 and divide them by 5. 6 .For Part III, Percent difference between the average value and the slope of the derivative diameter graph was found by doing this: ((slope of the derivative vs. diameter graph- average)/slope of derivative vs. diameter graph)*100 =67.9% VII. Analysis Questions/Answers 1. The Slope in Part I represents π 2.
