I am a 3D shape that has two parallel congruent bases. The bases can be any polygon and the faces are parallelograms.
Prism
The general formula for volume of any prism.
What is B x h ?

What is a cube?
The volume of the solid created by this net:

What is 27 cm3 ?
The base and top of this shape is a circle
Cylinder
The volume of a cone.
What is :
(pi*r^2*h)/3

What is a hexagonal prism?

The volume (v) created from the solid formed by the following net:

What is 120 in3?
My Base (B) is a Polygon and the formula for my volume (v) is:
(B*h)/3
What is a pyramid?
This formula was derived by dividing a cube into thirds.
Provide the name of the solid and the formula.
What is a pyramid.
and
What is:
(B*h)/3?

What is a cone?
The Volume (v) of the following solid:

What is 48 in3?
This 3D shape has NO sides and looks like a ball
What is a sphere? 
The formula for a cylinder
DAILY DOUBLE!!
Draw the net of a pyramid that has a regular polygon with 8 sides as its base.

The Volume (v) of the following solid:

What is 81.6 in3?
Area of Base = 10.2 in2 x 8 in (height)
If 2 shapes have the same base area and height then this is the same
Volume
The volume of a cone
What shape are the sides of any pyramid
triangles
The volume of this composite shape:

What is 890.12 cm3?
Volume of cone:
(pi*5^2*4)/3
+
Volume of cylinder:
(pi*5^2)*10
