Geometry – Surface Area

In this lesson we will learn:

• Prism surface area: Learn why ice is commonly shaped into cubes
• Pyramid surface area: Find a pyramid's surface area using squares and triangles
• Cylinder surface area: Unroll any cylinder to find its surface area!
• Cone surface area: Discover and use the formula for a cone's surface area!
• Sphere surface area: Find the total area of a sphere's curved surface
• Internal diagonals: What's the distance between opposite corners of a cube?

Prism is a three-dimensional figure with a pair of parallel and congruent ends, or bases. Prisms are identified by their bases and the sides of a prism are parallelograms.

Cube is a rectangular prism whose sides all have the same length.

The height of each triangle in the pyramid is called the slant height. The slant height of the pyramid is the altitude of one of the triangles.

Circumference is the distance around a circle (known as perimeter).

Radius is any segment from the center to a point on the circle and it is usually written as r

A cone is a three-dimensional(3D) figure with a single curved base that tapers to a single point called an apex with the base of a cone can be a circle or an oval of some type.

Sphere is a three-dimensional object that has the shape like a ball, to find volume of a Sphere Given a sphere that has radius r by using formula 4/3πr^3.

Volume is a measure of how much space a three-dimensional(3D) object occupies.
