Surface Area of Cube, Cylinder and Sphere
In this lesson we will look at calculating the surface area of a cube, cylinder and sphere.
CubesA 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
CylindersA 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.
SpheresA 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. <
