Get out lesson 24 from MondayWe need to fix number 4

• 4a• 3 sides 4 X 5 = 20+20+20• 2 sides 5 X 5 = 25+25• 4 interior walls 2 X 4= 8+8+8+8

• 2 holes 2X2 = (4+4)

• 4b

• Top/bottom 10 X 10 = 100+100• 4 sides 3X10=30+30+30+30• Interior walls 2X3=6+6+6+6

• Holes 2X2=(4+4)• Attached 4X5=(20)

agenda

• Finish lesson 24• Finish our question form yesterday• Start lesson 25• Exit ticket

Will the volume or the surface area of a 3-D

change when the shape is separated into

sections?

Same groups

• You will be given a rectangular prism• The prism maybe whole, or cut into pieces, the steps will be the same

• Fill the box or boxes with the corn pops. You can count them as you add them or you count them after you fill up the box/boxes.

Now using equations and calculation find volume• Formulas for volumes of solid shapes come from the same concept• (The area of the base)(height of shape)

• Base X height

• This works if base is circle (πr2) rectangle(bh) and triangle(1/2bh)

If you have more than one shape, find the volume of one and then add.
