FAQs on Surface Areas Questions Video Lecture - Mathematics (Maths) Class 10

1. What is the formula for calculating the surface area of a cube?
Ans. The surface area of a cube can be calculated using the formula: Surface Area = 6a², where 'a' is the length of one side of the cube.
2. How do you find the surface area of a cylinder?
Ans. The surface area of a cylinder can be found using the formula: Surface Area = 2πr(h + r), where 'r' is the radius of the base and 'h' is the height of the cylinder.
3. What is the difference between lateral surface area and total surface area?
Ans. The lateral surface area of a solid refers to the area of the sides excluding the top and bottom surfaces, while the total surface area includes the lateral area plus the area of the top and bottom surfaces.
4. How can I calculate the surface area of a sphere?
Ans. The surface area of a sphere is calculated using the formula: Surface Area = 4πr², where 'r' is the radius of the sphere.
5. What is the surface area of a rectangular prism?
Ans. The surface area of a rectangular prism can be calculated using the formula: Surface Area = 2(lw + lh + wh), where 'l' is the length, 'w' is the width, and 'h' is the height of the prism.
