Triangular Prism Triangular prisms are just like rectangular prisms, except that their square faces are triangles, making them three-sided prisms. Examples of real-life triangular prisms include: tents. wedges of watermelon. wedges of cheese.

• 2 Paperweights. Paperweights are decorative objects that come in glass, ceramic and hard plastic forms.

• 4 Christmas Decorations.

Telescopes, Cameras, Microscopes and Periscopes Other optical instruments that use prisms include telescopes, cameras, microscopes and even submarine periscopes. Telescopes use multiple prisms in a single unit as a means of manipulating light traveling great distances to meet the eye.

Examples of Cuboid

• The lunch box.
• Bricks.
• Shoebox.

• Cubicles.

Some examples of a sphere are: Earth. the Moon. basketballs.

The main difference between a cube and a cuboid is that a cube has six square-shaped faces of the same size but a cuboid has rectangular faces. A cuboid is rectangular-shaped and a cube is square-shaped.

Area is the space within the perimeter of a two-dimensional figure. Volume is the amount of space inside the bounds of a three-dimensional object.

To calculate the cube you need to have the dimensions of your freight in inches. Multiply the dimensions for each package then divide that amount by 1728 to get the cubic feet. Multiply the cubic feet by 10 to get the cubic weight (lbs).
