Topic: MS4.2 Surface Area and Volume
Calculates surface area of rectangular and triangular prisms and volume of right prisms and cylinders
3-D Shapes
An interactive flash widget that looks at 2D and 3D shapes. The 3D Shapes section steps through 1D, 2D then 3D. It also includes good pictures of various solids and their can be spun around.
Cubes
Investigate finding the volume of a prism.
“Fill a box with cubes, rows of cubes, or layers of cubes. The number of unit cubes needed to fill the entire box is known as the volume of the box.”
Interactivate: Surface Area and Volume
Interactives Geometry 3D Shapes
Geometry 3-D Shapes is an interactive Web site where students can learn about three-dimensional shapes, calculate surface area and volume, and discover some of the mathematical properties of shapes.
Nets (3D Models) : Free Printables
This generator prints a selection of nets for the construction of common 3D shapes.
Nets for the following polyhedra are included: cube, cuboid, cylinder, cone, regular pyramid, octahedron, rhombic prism, tetrahedron, icosohedron, hexagonal prism, hexagonal pyramid, pentagonal prism and pyramid.
Paper Models of Polyhedra
Polyhedra are beautiful 3-D geometrical figures that have fascinated philosophers, mathematicians and artists for millennia. On this site are a few hundred paper models available for free.
Surface Area
Investigate area as the total area of the surface of a space figure. Derive surface area formulas for common three dimensional figures.
Surface area of a cylinder
A reference for finding the surface area of a cylinder, includes a good animation.
Surface Area of a Prism
An interactive to check if you can find the surface area of a prism (rectangular and triangular).
Use Google Sketchup to visualise 3D shapes
A short video tutorial on creating 3D shapes in Google Sketchup to help students find the surface area.
