How to Find Slant Height
Description
A detailed tutorial on how to find the slant height. Step by step tutorial including several examples of how to find the slant height for reference.
Overview
The slant height is an additional measure of height that is used for the different types of triangular prisms. The common traingular prisms are your typical pyramid, and cones. On a pyramid, the slant height is the height of one of the triangular faces. On a cone, the slant height is to be found using a formula that is only for the cone. It is the square root of the radius squared added to the real height squared.

Overview of Sides and Bases of Polyhedrons
Description
A detailed tutorial on sides and bases of polyhedrons. Step by step tutorial including several examples of sides and bases of polyhedrons for reference.
Overview
Sides and bases of polyhedrons are more commonly known as faces of 3D geometrical shapes. Typically on a polyhedron you will have 2 bases and several sides, although there are exceptions to that rule. The cylinder only has one side, and the triangular prism, or pyramid, only has one base. You can identify the base because it is a unique shape on the polyhedron. Everything else is a side. This only applied to your normal polyhedron shapes such as prisms.

An Overview of Composite Solids
Description
A detailed tutorial on what a composite solid is. Step by step tutorial including several examples of composite solids for reference.
Overview
A composite solid is exactly the same as a composite figure, only it is in 3D instead of in 2D. It is any kind of polyhedron (like a prism or a pyramid) that can be split into two or more of the basic types of polyhedrons in order to solve for the volume of the figure. Composite solids are very rare, and there are no regular types of solids that would be considered a composite solid.

How to Find the Surface Area of a Rectangular Prism
Description
This video displays how to find the surface area of a rectangular prism. The different parts of a rectangular prism are explained in detail. One sample problem is worked through in the video to show how to correctly apply the formula.
Overview
The surface area is the area of each side, or face, of the shape added together. Rectangular prisms have 6 sides, which consist of 3 pairs. This makes solving for a rectangular prism’s surface area a bit easier. In order to solve for the surface area, you need to solve for the area of each face seperately, first. All the faces of a rectangular prism are rectangles, so the area can be found using this formula: A = l * w. You only have to solve for this three times – the matching face (found exactly opposite of the one you solved for) will have the same area, so just multiply your result by 2. After doing this three times, add them all together. Your result is the surface area.

How to Find the Volume of a Rectangular Prism
Description
This video explains what a rectangular prism is and then gives and explains the formula to find the volume of a rectangular prism. This video provides two sample problems with easy to understand steps and solutions.
Overview
A rectangular prism is really just a rectangle in 3D. The volume of a rectanglur prism can be expressed like this:
V = l * w * h
Where l is the length, w is the width, and h is the height. This differs from an area formula because in an area formula there is no height, only a length and width.
