  5. Last lesson you were again asked to write down 1 thing you would do during this lesson that would improve your learning. To begin today’s lesson, write down that goal at the top of your paper.

  6. Find the volumes of prisms and cylinders. • volume • cylinder • complex solid

  7. Standard 7MG2.1 Use formulas routinely for finding the perimeter and area of basic two-dimensional figures and the surface area and volume of basic three-dimensional figures, including rectangles, parallelograms, trapezoids, squares, triangles, circles, prisms, and cylinders. Standard 7MG2.2 Estimate and compute the area of more complex or irregular two- and three-dimensional figures by breaking the figures down into more basic geometric objects.

  8. Find the Volumes of Prisms Find the volume of the rectangular prism. Volume of a prism Simplify. Answer: The volume is 385 cubic inches.

  9. Find the volume of the rectangular prism. • A • B • C • D A. 90 in3 B. 120 in3 C. 126 in3 D. 148 in3

  10. The base is a triangle, so B = Find the Volumes of Prisms Find the volume of the triangular prism. Volume of a prism The height of the prism is 4. Simplify. Answer: The volume is 270 cubic feet.

  11. Find the volume of the triangular prism. • A • B • C • D A. 22 ft3 B. 30 ft3 C. 37 ft3 D. 45 ft3

  12. Find the Volume of a Cylinder Find the volume of the cylinder. Round to the nearest tenth. Volume of a cylinder Replace r with 3 and h with 12. Simplify. Answer: The volume is about 339.3 cubic centimeters.

  13. Find the volume of the cylinder. Round to the nearest tenth. • A • B • C • D A. 140.1 in3 B. 152.5 in3 C. 169.6 in3 D. 183.4 in3

  14. Find the Volume of a Complex Solid TOYS A wooden block has a single hole drilled entirely through it. What is the volume of the block? Round to the nearest hundredth. Problem Solving Alert! Take a moment & write down the steps you’d take to solve this. Compare your steps to what the slide show suggests.

  15. Find the Volume of a Complex Solid Rectangular Prism Cylinder Answer: The volume of the box is about 72 – 9.42 or 62.58 cubic centimeters.

  16. HOBBIES A small wooden cube has been glued to a larger wooden block for a whittling project. What is the volume of the wood to be whittled? • A • B • C • D A. 98 in3 B. 104 in3 C. 112 in3 D. 115 in3

  17. Reflect upon how you participated in the lesson today. Ask yourself: “What part of the lesson today did I not get? Did I ask for help? What am I going to do now to try and figure it out?” Write down what you will do to better understand that one part of the lesson you had difficulty with.
