3-Dimensional Shapes

SOLIDS
Our world is made up of lots of shapes. We will look at solids such as prisms, cubes, cones, spheres, pyramids, and cylinders. We can create 3-D shapes by folding paper. We will use some nets to help create the shapes we are studying.
When working with 3-D shapes we can find the volume of the shapes. The volume is the capacity that the shape can hold. It is measured in cubic units. We can also find the surface area of the shape. The surface area is the total area of all the faces on the shape. Surface area is measured in square units.
Isometric dot paper is used to draw three-dimensional shapes. Click here to print out a sheet and try to draw some of the shapes that we are studying in this unit. Make sure the line segments end on two dots.

Rectangular Prism Net
First predict what shape will result from folding the Net, then cut out this net and construct a 3-D shape. Fold it along the dark edges. Use small pieces of tape on the flaps to hold the sides together. What shape does it make? |
