FAQs on Surface Area and Volume Class 10 Worksheet Maths
| 1. What are the formulas for calculating the surface area and volume of a cube? |  |
Ans. The surface area of a cube is calculated using the formula \(6a^2\), where \(a\) is the length of a side of the cube. The volume of a cube is calculated using the formula \(a^3\).
| 2. How do you find the surface area and volume of a cylinder? | |
Ans. The surface area of a cylinder can be found using the formula \(2\pi r(h + r)\), where \(r\) is the radius and \(h\) is the height. The volume of a cylinder is calculated using the formula \(\pi r^2 h\).
| 3. What is the difference between surface area and volume? | |
Ans. Surface area refers to the total area that the surface of a three-dimensional object occupies, while volume refers to the amount of space that the object occupies. Surface area is measured in square units, while volume is measured in cubic units.
| 4. How do you calculate the surface area and volume of a sphere? | |
Ans. The surface area of a sphere is calculated using the formula \(4\pi r^2\), where \(r\) is the radius. The volume of a sphere is calculated using the formula \(\frac{4}{3}\pi r^3\).
| 5. Can you explain how to find the surface area and volume of a cone? | |
Ans. The surface area of a cone is calculated using the formula \(\pi r(l + r)\), where \(r\) is the radius and \(l\) is the slant height. The volume of a cone is calculated using the formula \(\frac{1}{3}\pi r^2 h\), where \(h\) is the height of the cone.
