What are the formulas of mensuration?
3D Figures Mensuration Formulas
| Volume | Curved Surface Area/Lateral Surface Area | Nomenclature |
|---|---|---|
| l x b x h | 2h(l+b) | Length = l Breadth = b height = h |
| πr2 x h | 2πrh | Radius of base = r |
| 1/3πr2h | πrl | Slant height = s |
| 4/6 πr3 | 3πr2 | Radius = r |
What is the area of square formula?
The area of a square is calculated with the help of the formula: Area = s × s, where, ‘s’ is one side of the square. Since the area of a square is a two-dimensional quantity, it is always expressed in square units.
Who invented mensuration?
Answer: The mensuration was discovered by Archimedes.
What is 2D and 3D in mensuration?
If a shape is surrounded by three or more straight lines in a plane, then it is a 2D shape. If a shape is surrounded by a no. of surfaces or planes then it is a 3D shape. These shapes have no depth or height.
Who introduced mensuration?

What is pi value?
Succinctly, pi—which is written as the Greek letter for p, or π—is the ratio of the circumference of any circle to the diameter of that circle. Regardless of the circle’s size, this ratio will always equal pi. In decimal form, the value of pi is approximately 3.14.
What is mensuration brief?
Mensuration is the branch of geometry that deals with the measurement of area, length, or volume in 2D and 3D shapes. Mensuration includes computation using mathematical formulas and algebraic equations.
What is called mensuration?
Mensuration is the branch of mathematics that studies the measurement of geometric figures and their parameters like length, volume, shape, surface area, lateral surface area, etc. Learn about mensuration in basic Mathematics.
