Surface Area of Cube, Cylinder, Sphere and Rectangular Prism

In this lesson we will look at calculating the surface area of a cube, cylinder, sphere and rectangular prism.

Cubes

A cube is a three-dimensional figure with six matching square sides.

The figure above shows a cube. The dotted lines indicate edges hidden from your view.

If s is the length of one of its sides, the

Surface area of a cube = 6s²

Cylinders

A cylinder is a solid with two congruent circles joined by a curved surface.

In the above figure, the radius of the circular base is r and the height is h. The volume of the cylinder is the area of the base × height.

Spheres

A sphere is a solid with all its points the same distance from the center.

The following video will show examples on how to calculate the area of a cube, cylinder and sphere.

The following video shows how to calculate the surface area of a rectangular prism.
