Applied Geometry
Lesson: 12 – 2
Surface Areas of Prisms & Cylinders
Objective:
Learn to find the lateral areas and surface areas of prisms and
cylinders.

3. Lateral Area (of a solid) – the sum of all the areas of the lateral sides
Surface Area (of a solid) – the sum of the areas of all it surfaces.
Volume (of a solid) - measures the space contained within a solid.

4. Abbreviations h – height P – Perimeter of base B – Area of base
d – diameter
r – radius
l - Slant Height

5. Activity Use geometric shapes to find formulas. Prisms
Lateral Area L = Ph
Surface Area S = Ph + 2B
Volume V = Bh
Pyramids
Lateral Area L = ½ P l
Surface Area S = ½ P l + B
Volume V = (1/3)Bh

6. Cylinders
Lateral Area
Surface Area
Volume
Cone
Sphere

7. Activity
Net - a two-dimensional pattern that folds to form a solid.

8. Find the lateral area and the surface area of the rectangular prism.

9. Find the lateral area and surface area of the triangular prism.
Find c first.

10. Find the lateral area and surface area of the cylinder to the nearest hundredth.
