FAQs on Mind Map: Surface Area & Volumes - Mathematics (Maths) Class 10

1. What is the formula to calculate the surface area of a cube?
Ans. The formula to calculate the surface area of a cube is 6a², where 'a' is the length of one side of the cube. This is because a cube has six identical square faces, and the area of one square face is a².
2. How do you find the volume of a cylinder?
Ans. The volume of a cylinder can be found using the formula V = πr²h, where 'r' is the radius of the base and 'h' is the height of the cylinder. You multiply the area of the circular base (πr²) by the height (h).
3. What is the difference between surface area and volume?
Ans. Surface area is the total area that the surface of a three-dimensional object occupies, while volume measures the space that the object occupies. Surface area is measured in square units, whereas volume is measured in cubic units.
4. How do you calculate the surface area of a cone?
Ans. The surface area of a cone can be calculated using the formula SA = πr(r + l), where 'r' is the radius of the base and 'l' is the slant height of the cone. This formula includes the area of the base (πr²) and the lateral surface area (πrl).
5. What is the volume of a sphere?
Ans. The volume of a sphere is calculated using the formula V = (4/3)πr³, where 'r' is the radius of the sphere. This formula gives the total space inside the sphere.
