CATALYST (10 minutes, individual work): Convert 20 hours to minutes. Assignment #7 Volume of Irregular Solids LO: Be able to find volume of a rectangular prism, liquid, and irregular solid. EQ: How do you find the volume of an irregular solid? LEVEL ZERO VOICE CATALYST (10 minutes, individual work): Convert 20 hours to minutes. Rebecca walked 6 mi/hr for 2 miles. How long did she walk? Calculate the volume of a rectangular prism with: Length: 3 cm Width: 2 cm Height: 1 cm Calculate the volume of this prism: 3/10-3/11 AGENDA Lecture Volume Activity HOMEWORK Worksheets
How to Find Volume: Rectangular prism: V= l x w x h Liquid: graduated cylinder
Quickdraw: Polyvinyl chloride is more dense than polyethylene. Draw a picture of how you think the molecules might be arranged or look different from each other. Draw a thought bubble when you are done.

How to Find Volume: Rectangular prism: V= l x w x h Liquid: graduated cylinder What about an irregular solid?!?!!?!?!
How to Find Volume: Rectangular prism: V= l x w x h Liquid: graduated cylinder Irregular solid: displacement method **irregular solid: three-dimensional object that does not have a normal shape, maybe different side lengths
How to Find Volume: Rectangular prism: V= l x w x h Liquid: graduated cylinder Irregular solid: displacement method The Displacement Method Measure out some water in graduated cylinder Drop in irregular solid Find new volume of water New volume – old volume = volume of solid
New volume:270 cm3 Old volume: 200 cm3 VolRock = VolNew - VolOld 270cm3 - 200cm3 = 70cm3 Volume of rock: 70cm3
Use water displacement method to find the volume
Use scale to find the mass Plug into D=m/v
1 cm3 = 1 mL
