Homework

Questions about the homework?

Surface Area

What is Surface Area?-The sum of the areas of all surfaces of a figure.

What are lateral faces?-The faces that connect to the base of a prism or pyramid.

What is a lateral surface?- The curved surface of a cylinder or cone.

Cylinders and Prisms

Cylinder: A three dimensional figure with two parallel, congruent circular bases connected by a curved lateral surface.

Prism: A three dimensional figure that has two congruent, polygon-shaped bases and other faces that are all parallelograms.

Prisms

Formula

S= 2B+PhS – Surface AreaB- Area of baseh- height of figure (distance from base to base)P- Perimeter of the BASE

Example #1

1)

15 m7 m

8 m

Area of Base: 15 x 7 = 105Perimeter of Base: 15+7+15+7 = 44 S= 2 (105) + 44 (8) = 562 m2

Example #2

2)

12 cm12 cm

12 cm

Area of Base: 12 x 12 = 144Perimeter of Base: 12+12+12+12 = 36 S= 2 (144) + 36 (12) = 720 m2

You try the rest!!

With your group members try examples 3-6.

First ones to finish get to put their answers on the board!
