FAQs on Flashcards: Surface Area of Different Shapes Video Lecture - Mathematics (Maths) Class 9

1. What is the formula for finding the surface area of a cube?
Ans. The formula for finding the surface area of a cube is SA = 6s^2, where s is the length of one side of the cube.
2. How do you calculate the surface area of a cylinder?
Ans. To calculate the surface area of a cylinder, you can use the formula SA = 2πr^2 + 2πrh, where r is the radius of the base and h is the height of the cylinder.
3. What is the formula for finding the surface area of a sphere?
Ans. The formula for finding the surface area of a sphere is SA = 4πr^2, where r is the radius of the sphere.
4. How do you determine the surface area of a rectangular prism?
Ans. To determine the surface area of a rectangular prism, you can use the formula SA = 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height of the prism.
5. What is the formula for finding the surface area of a cone?
