#VOLUME OF TRAPEZOIDAL PRISMS INVESTIGATION PLUS#

Since the bases for a prism or cylinder areĬongruent, this is often expressed as twice the area of the base.

The surface area of a prism or cylinder is the lateral area plus theĪrea of each base. The surface area of a figure is the sum of the area of all surfaces of a figure. It depends on if you can obtain the altitude (slant height) of each triangular face. (which is a fancy way to say you may need calculus). The surface area might not be calculatable using elementary techniques If the pyramid is irregular and certainly if the cone is oblique, Of the base where it is halfway between the base's vertices.

The slant height is the distance from the vertex to the edge The lateral area is thus half the slant height times the perimeter. Prisms, but since each face is a triangle (or triangle-like), The lateral area of a regular pyramid or right cone is similar to that of Lateral Area of a right cone: ½ perimeter × slant height. Lateral Area of a regular pyramid: ½ perimeter × slant height. Lateral Area of a cylinder: circumference × height. Lateral Area of a prism: perimeter × height Multiply this length by the width, which was the height of the can. To find the area of this rectangle which is the same as the lateral area, What was the circumference of the base is now the length of a rectangle. Now cut down the side of the can and roll it flat. The lateral area is the surface area of a 3D figure, Volume: prism/cylinder, pyramid/cone, sphere.Surface Area: prism/cylinder, pyramid/cone, sphere.Lateral Area: prism/cylinder, pyramid/cone.
