Three-Dimensional Measurement and Application

Lesson 18

Math

Unit 6

10th Grade

Lesson 18 of 18

Objective


Apply constraints on volume, surface area, or cost to solve design problems with three-dimensional figures.

Common Core Standards


Core Standards

  • G.GMD.A.3 — Use volume formulas for cylinders, pyramids, cones, and spheres to solve problems.
  • N.Q.A.2 — Define appropriate quantities for the purpose of descriptive modeling.
  • N.Q.A.3 — Choose a level of accuracy appropriate to limitations on measurement when reporting quantities.
  • G.MG.A.2 — Apply concepts of density based on area and volume in modeling situations (e.g., persons per square mile, BTUs per cubic foot). Modeling is best interpreted not as a collection of isolated topics but in relation to other standards. Making mathematical models is a Standard for Mathematical Practice, and specific modeling standards appear throughout the high school standards indicated by a star symbol (★). The star symbol sometimes appears on the heading for a group of standards; in that case, it should be understood to apply to all standards in that group.
  • G.MG.A.3 — Apply geometric methods to solve design problems (e.g., designing an object or structure to satisfy physical constraints or minimize cost; working with typographic grid systems based on ratios).

Criteria for Success


  1. Define density as the amount of one quantity per square or cubic unit of another. 
  2. Identify a general plan for the solution of problems and revise this plan as necessary throughout. 
  3. Describe the level of precision necessary at different stages of the problem to determine the most accurate answer.
  4. Identify information that is necessary to determine an accurate solution.
  5. Describe how you will assess whether your solution is reasonable or not.
  6. Justify the solution and process of solving the problem. 

Tips for Teachers


  • The criteria for success are repeated in Lessons 16–18, which all focus on modeling. In lesson 18, we are focusing on applications of volume and surface area with constraints and design problems. 
  • There is no Target Task and little Problem Set Guidance in this lesson due to the level of work and explanation required for the two Anchor Problems. During the lesson, be sure to mix in plenty of independent work time and feedback cycles to ensure adequate thinking and processing time.

Anchor Problems

25-30 minutes


Problem 1

The Fresha Drink Company is marketing a new soft drink. The drink will be sold in a can that holds 200 cubic centimeters. In order to keep costs low, the company wants to use the smallest amount of aluminum. Find the radius and height of a cylindrical can that holds 200 cubic centimeters and uses the smallest amount of aluminum. Explain your reasons and show all your calculations.

Problem 2

Janine is planning on creating a water-based centerpiece for each of the 30 tables at a party she is throwing. She has already purchased a cylindrical vase for each table. The radius of the vase is 6 centimeters and the height is 28 centimeters. She will fill the vases halfway with water and then add a variety of colored marbles until the water line is approximately three-quarters of the way up the cylinder. The small marbles, 9 millimeters in radius, come in bags of 100 and cost $3. The large marbles, 12 millimeters in radius, come in bags of 100 and cost $4. 

  1. If Janine only bought 9-millimeter marbles, how much would she spend on marbles for the whole party? What if Janine only bought 12-millimeter marbles?
  2. Janine’s parents, who are paying for the party, have told her she can spend, at most, $180 on the marbles. Below is a system of inequalities that she can use to determine how many marbles of each type she can buy, where $$x$$ represents the number of bags of 9-millimeter marbles and y represents the number of bags of 12-millimeter marbles. Annotate each inequality with what it represents in terms of the problem.

$$\left\{\begin{matrix} 3x+4y\leq 180\\ 100(.972\pi)x+100(2.304\pi)y\geq 30(252\pi) \end{matrix}\right.$$

  1. Janine graphed the system of inequalities to determine her possibilities. Which inequality represents each portion of the graph? From the graph, what are some possibilities of combinations of marbles that Janine could buy?
