FAQs on Surface Areas and Volumes Video Lecture - Mathematics Olympiad for Class 9
| 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 6 times the square of its side length. So, if 'a' is the side length of the cube, the surface area is given by 6a².
| 2. How can I find the volume of a sphere? | |
Ans. The volume of a sphere can be calculated using the formula (4/3)πr³, where 'r' is the radius of the sphere. Simply substitute the value of the radius into the formula to find the volume.
| 3. Is there a formula to find the surface area of a cylinder? | |
Ans. Yes, the formula to calculate the surface area of a cylinder is 2πrh + 2πr², where 'r' is the radius of the base and 'h' is the height of the cylinder. Multiply the curved surface area of the cylinder (2πrh) by 2, and add the area of the two bases (2πr²) to find the total surface area.
| 4. How do I calculate the volume of a cone? | |
Ans. To find the volume of a cone, you can use the formula (1/3)πr²h, where 'r' is the radius of the base and 'h' is the height of the cone. Plug in the values of the radius and height into the formula to calculate the volume.
| 5. What is the surface area of a cuboid? | |
Ans. The surface area of a cuboid is given by the formula 2(lw + lh + wh), where 'l' represents the length, 'w' represents the width, and 'h' represents the height of the cuboid. Add the areas of all six faces (two length x width, two length x height, and two width x height) to find the total surface area.
