13 in

2. 1.
SA = Front + Back + Left + Right + Top + Bottom
SA = (lh) + (lh) + (wh) + (wh) + (lw) + (lw)
SA = (10)(4) + (10)(4) + (3)(4) + (3)(4) + (10)(3) + (10)(3)
SA =
SA = 164 cm2

3. 2.
SA = Top + Bottom + Side
SA = (r2) + (r2) + (lw)
SA = (r2) + (r2) + (circumference)(height)
SA = (r2) + (r2) + (2r)(h)
SA = (3.14)(8)2 + (3.14)(8)2 + (2)(3.14)(8)(9)
SA = ft2

4. SA = Front + Back + Left + Right + Bottom
13 in 3.
SA = Front + Back + Left + Right + Bottom
SA = 334 in2

5. 4.
SA = Side 1 + Side 2 + Side 3 + Bottom
SA = 38 ft2

6. Lesson 10.6 and 10.7: Volume of Prisms and Cylinders
Volume of prism or cylinder =
(Area of base)(height of polyhedron)
Ex. Rectangular prism: Base is rectangle so,
V = (area of base )(Height polyhedron)
V = (l w) (H)
V = lwH
height
width
length

7. Volume of triangular prism=
(area of triangular base) (height of polyhedron)
Example:
V = (area of triangular base)(height of polyhedron)
height
Height
base
Where h = height of triangular polygon
H = height of polyhedron (prism)

8. Volume of cylinder = (area of circular base)(height of cylinder)
Example:
radius
Where r = radius
H = height of cylinder
height

9. V = (area of base)(height) V = (area of rectangle)(height) V = (lw)(h)
Examples: p #3
V = (area of base)(height)
V = (area of rectangle)(height)
V = (lw)(h)
V = (10)(3)(4)
V = 120 cm3

10. p. 554, #5
V = (area of base)(height)
V = (area of circle)(height)
V = (r2)(h)
V = (3.14)(8)2(9)
V = ft3

11. p.554 # 6
V = (area of base)(Height of prism)
V = (area of triangle)(Height of prism)
V = 270 in3
