TABE Surface Area

What is the formula for the Area of a Circle?

• $A=\frac{1}{2}bh$

• $A=\pi r^2$

• $A=bh$

What is the formula for the Area of a Triangle?

• $A=\frac{1}{2}bh$

• $A=\pi r^2$

• $A=bh$

 $V=Bh$  

 $S=Ph+2B$  

The big B in the equations for volume and surface area means...

• The AREA of the BASE.

• The Circumference of the BASE.

• The PERIMETER of the BASE.

• the distance between the two bases.

 $S=Ph+2B$  
The big P in the equations for surface area means...

• The AREA of the BASE.

• The Circumference of the BASE.

• The PERIMETER of the BASE.

• the distance between the two bases.

When you find the total surface area using the formula  $S=Ph+2B$  you have to determine what is the BASE.  The BASE of a TRIANGULAR t prism will be the...

• side on the bottom of the picture.

• one of the triangles.

• any of the rectangles.  Pick one and use that as the base.

• side on the bottom of the picture. (Like the floor)

• one of the triangles.

 $S=Ph+2B$  
The little  $h$   in the equations for surface area means...

• The AREA of the BASE.

• The Circumference of the BASE.

• The PERIMETER of the BASE.

• the distance between the two bases.

 $S=Ph+2B$  
What is the shape of the BASE?

• rectangle

• circle

• triangle

 $S=Ph+2B$  

What is the AREA of the BASE?

• $24\ cm^2$

• $8\ cm^2$

• $12\ cm^2$

•  $17\ cm^2$ 

 $S=Ph+2B$  

What is the PERIMETER of the BASE?

•  $24\ cm^{ }$ 

•  $8\ cm^{ }$ 

•  $12\ cm^{ }$ 

•  $17\ cm^{ }$
