Question

easy trick to learn formulas of volume

Answer 1

1. Understand concept of Length, Area (2D), Volume (3D)

2.Understand the basic shapes of Geometry what are relations and differences among different shapes.

3.Then relate formulae with relative shapes and understand the logic behind them. Pick real life shapes and observe them very well.

4.Convert formulae in mental language like instead A=x^2 learn this way Area of square is square of side. twice of square root of side becomes diagonal.

5.Frequently recall formulae. In real life whenever you find geometrical figure try to recall formulae, concepts of that figure

6.Always write applicable formulae when you solve questions.

Answer 2

1.Volume Of cube= a^3

This is very easy to remember

2. Volume of cuboid=l×b×h

This is also easy

3. Volume of cylinder= πr^2h

Remember this, it will help you in remembering others I will show how

4. Volume of cone =1/3× area of cylinder

= 1/3× πr^2h

5. volume of sphere= 4/3πr^3

See , here there is no height , therefore we take r^2×h= r^2×r=r^3

6. Volume of hemisphere

= 1/2 volume of sphere

=1/2×πr^3
