Name of Shape | Explanation | Curved Surface Area | Total Surface Area | Volume |
Cube | All the sides of a cube are equal, and suppose that the length of each side in a cube is ‘a’. | 4a^{2} | 6a^{2} | a^{3} |
Cuboid | Let the length, breadth, and height of the cuboid be ‘l’, ‘b’, and ‘h’, respectively. | 2 (l + b) h | 2 (lb + bh + hl) | lbh |
Right Circular Cylinder | Let the radius of the cylinder be ‘r’, and the height be ‘h’. | 2πrh | 2πr(h + r) | πr^{2}h |
Right Circular Cone | Let the radius of the cone be ‘r’, and the perpendicular height from vertex to base be ‘h’. Let the length of the cone be ‘l’. | πrl | πr(l + r) | (⅓)π r^{2}h |
Sphere | Let the radius of the sphere be ‘r’. | 4πr^{2} | 4πr^{2} | 4/3)πr^{3} |
Solid Hemisphere | Let the radius of the sphere be ‘r’. | 2πr^{2} | 3πr^{2} | 2/3πr^{3} |
Hollow Hemisphere | Let the radius of the shape be ‘r’. | 2πr^{2} | 2πr^{2} | 2/3πr^{3} |
