3. What are some common formulas used in mensuration?
Ans. Some common formulas used in mensuration include the area of a triangle (1/2 * base * height), the circumference of a circle (2 * π * radius), and the volume of a cylinder (π * radius^2 * height).
4. How can I calculate the surface area of a three-dimensional shape?
Ans. To calculate the surface area of a three-dimensional shape, you need to find the sum of the areas of all its faces. For example, to find the surface area of a cube, you can calculate 6 times the area of one of its faces.
