1. Today’s Lesson: What: volume of prisms and cylinders Why: To calculate the volume of both rectangular prisms and cylinders. What: volume of prisms and cylinders Why: To calculate the volume of both rectangular prisms and cylinders.

2. 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

3. Key words for volume:

4. Volume of a PRISM: 1) V = lwh 12 cm 5 cm 4 cm 240 cm. ³

5. Volume of a PRISM: 2) V = lwh 3.5 cm 14 cm 98 cm. ³ 2 cm

6. Volume of a PRISM: 3) V = lwh 7 cm 343 cm. ³

7. Volume of CYLINDERS: 1) V = r²h 15 cm 4 cm 188.4 cm. ³

8. Volume of CYLINDERS: 2) V = r²h 4.5 cm 2.5 cm ≈ 88.3 cm. ³

9. Volume of CYLINDERS: 3) V = r²h 10 cm 6 cm 282.6 cm. ³

10. 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

11. 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
