Get out your notebook and prepare to take notes on Section 10.5/10.7
Find the area of the following irregular figure:
10.5/10.7 – Surface Area and Volume of Prisms
(Page 551 & 563)Essential Question:
How do we find the surface area and volume of prisms?
ReviewSolids:
DO NOT lie in a plane Have length, width, and height
Common Solids:1. Prism2. Pyramid3. Cylinder4. Cone5. Polyhedron6. Sphere
10.5 – Surface Area of PrismsPrism:
Two parallel bases that are congruent polygonsLateral faces are parallelogramsNamed by the shape of its bases
^^PENTAGONAL PRISM^^
10.5 cont.Example 1:
For the following figure, describe the bases, name the figure, and name the part labeled
Bases: OCTAGONS
Figure: OCTAGONAL PRISM
: LATERAL EDGE OR BASE EDGE
10.5/10.7 - ClosureHow do we find the surface area and volume of
prisms?
Surface Area: Find the lateral area and add it to the area of the
bases
VolumePrism:
