Today’s Lesson: What: volume of prisms and cylinders Why: To calculate the volume of both rectangular prisms and cylinders.
Vocabulary: Rectangular Prism-- a 3-D figure that is comprised of six ____________faces (a “box”). Cube– a special type of ____________________ where each face is a ___________________. Cylinder– a 3-D figure with circular __________________ for both the top and the bottom. Radius-- refers to the line segment that __________________________ in the center and extends to the circumference line (edge). Diameter– refers to the line segment that extends the entire way _______________ a circle. The diameter splits the circle into two _____________ halves. Volume— the measure of ___________ occupied by a solid region. rectangular rectangular prism square faces begins across equal space
V = lwh Volume of a PRISM: 5 cm 4 cm 12 cm 240 cm.³
V = lwh Volume of a PRISM: 2) 2 cm 14 cm 3.5 cm 98 cm.³
V = lwh Volume of a PRISM: 3) 7 cm 343 cm.³
V = 𝛑r²h Volume of CYLINDERS: 1) 4 cm 15 cm 188.4 cm.³
V = 𝛑r²h Volume of CYLINDERS: 2) 2.5 cm 4.5 cm ≈ 88.3 cm.³
V = 𝛑r²h Volume of CYLINDERS: 3) 6 cm 10 cm 282.6 cm.³
Volume word problems: 1) MaryBeth is filling a sandbox with sand. If the sandbox is seven feet in length, two feet in height, and four feet in width, how much sand can the sandbox hold? 56 ft.³
Volume word problems: 2) Joe is pouring coffee into his coffee mug. The mug is 7 in. tall, and its bottom has a diameter of 4 in. How much coffee does Joe’s mug hold? 87.92 in.³
END OF LESSON The next slides are student copies of the notes for this lesson. These notes were handed out in class and filled-in as the lesson progressed. NOTE: The last slide(s) in any lesson slideshow (entitled “Practice Work”) represent the homework assigned for that day.
