Try moving these squares around to make different nets of Cubes

Net of a Rectangular Prism

Question 1

Is a cube a prism?

Question 2

Which face of a cube is the base of the cube (rectangular prism)?

Question 3

Make the net of the rectangular prism above into the net of a square prism and then into the net of a cube. (All of the faces of a cube must be square, however, a square prism only needs to have a square base.)[br][br][i]Hint: [/i]It may be easier to fold the net so that it is a solid and then change the dimensions so that you have the desired shape, before unfolding it to look at the net.

Question 4

a. Enclose the rectangular prism net, so that it resembles a solid.[br][br]b. Rotate the prism to find a top, side and bottom view of the solid.[br][br]c. Use these views to help you answer the questions on the worksheet, it might help to sketch the views and label each face with a title "Top, side and bottom views of rectangular prisms."[br][br]d. Do the same for a square prism and a cube

Net of a Cylinder (Prism with a circular base)

[size=200]Pyramids[br][/size]

Net of a Square Pyramid

Net of a Cone (Pyramid with a circular base)

Question 5

What shape is the base of a cone?

Question 6

What shape is the base of a triangular prism?

Question 7

What shape is the base of a square pyramid?

Question 8

What shape is the base of a cylinder?

A triangular prism that has been knocked over!

Question 9

a. What is the base of the prism on the left?[br][br]b. What is the base of the prism on the right?[br][br]c. Does the base of the shape change depending on how the shape is positioned?
