## FAQs on Surface Area Video Lecture - Crash Course: Class 10

 1. What is surface area?
Ans. Surface area refers to the total area of the outer surface of a three-dimensional object. It includes the areas of all the faces of the object, including its base(s) and lateral faces.
 2. How is the surface area of a cube calculated?
Ans. The surface area of a cube is calculated by finding the sum of the areas of all its six faces. Since all the faces of a cube are identical squares, the surface area can be calculated by multiplying the length of one side of the cube by itself, and then multiplying the result by six.
 3. How is the surface area of a cylinder calculated?
Ans. The surface area of a cylinder is calculated by adding the areas of its two circular bases and its curved surface. The formula for the surface area of a cylinder is 2πr^2 + 2πrh, where r is the radius of the base and h is the height of the cylinder.
 4. What is the difference between surface area and volume?
Ans. Surface area refers to the total area of the outer surface of a three-dimensional object, while volume refers to the amount of space occupied by the object. Surface area is measured in square units, while volume is measured in cubic units.
 5. How is the surface area of a cone calculated?
Ans. The surface area of a cone is calculated by adding the area of its base and its curved surface. The formula for the surface area of a cone is πr^2 + πrl, where r is the radius of the base and l is the slant height of the cone.
