3-18-13 Volume of a Rectangular Prism

EQ: How do you find the volume of a rectangular prism? How does the area of the base affect the volume?

BOP : What is surface area? What is volume?

DWP: Find the surface are of the rectangular prism.

5 m

5 m

10 m

Foldable

Make a foldable for

formulas for prisms and cylinders.

Keep this in your notebook for reference.

FORMULAS

The fold crease

FoldableFold over the top cut section and label each section on the outside. Do the same thing for the other shapes.

Reopen the fold

Rectangular Prism

6. Reopen the fold.

The fold crease

FoldableReopen the fold.

*Draw each shape

*Write the general formula for surface area of a rectangular prism.

*Write the general formula for volume of

A rectangular prism

Rectangular Prism

Triangular Prism

Square pyramid

Cylinder

Compound Figures

FOR FINDING

SURFACE AREA

SA = ph + 2B

Volume = Bh

V = area of the base(h)

*B=area of the base

Back

Side 2

Side 1

Front

Bottom

Surface Area

Height (H)

Breadth (B) or width

Length (L)

Surface area is the area of each face added together. If you know the area of three faces, then you can find the total area because the area of the top and bottom are the same, the area of the front and back are the same and the area of the sides are the same.

SA =2πrh + 2 πr2

*The circumference of the circle is the length of the rectangle

Volume = Bh

V = area of the base(h)

V = πr2h

*B=area of the base is a circle

Volume = Bh

*B is the area of the base

of the base?

2. How many 1 cm cubes

would it take to cover the base? (l x w)

3. How many layers of 1 cm cubes would it take to fill the prism? (l x w x h)

of the base?

3. How many layers of 1 cm cubes would it take to fill the prism? (l x w x h)

Summary : How does the area of the base

affect the volume of a rectangular prism?
