In this lesson we’ll look at an introduction to three-dimensional geometric figures, specifically nets, volume, and surface area of prisms. We want to be able to find the net and calculate the volume and surface area for different types of prisms, like rectangular, triangular, etc.
Read MoreThe ratio of the surface area, S, to the volume, V, can be expressed as a fraction S/V, or converted to a decimal. In order to find the ratio of the surface area to the volume, we have to first find the surface area of the prism and the volume of the prism.
Read MoreA right circular cylinder (the only kind of cylinder we’re dealing with in this lesson) has a pair of parallel, congruent circular bases. We only need a few pieces of information about the net, or volume, or surface area, in order to find the rest of the values for the cylinder.
Read MoreIn this lesson we’ll look at the volume and surface area of spheres. A sphere is a perfectly round ball; it’s the three-dimensional version of a circle. There are specific formulas we need to use to find the volume of a sphere and the surface area of a sphere.
Read MoreThe diagonal of a right rectangular prism goes from one corner of the prism, across the interior volume, all the way to the opposite corner of the prism.
Read MoreA pyramid has one base made of any shape and the rest of the faces are triangles. The pyramid is named by the shape of its base.
