Shortcut Methods and Tricks to Solve Numerical Examples#

For NEET:

1. Total Leaf Area:

   • Shortcut: Multiply the number of leaves by the leaf area per leaf.

2. Volume of a Cylinder (Tree Trunk):

   • Trick: Consider the trunk as a cylinder and use the formula for the volume of a cylinder: $V = \pi r^2 h$, where $r$ is the radius of the trunk and $h$ is the height of the trunk.

3. Total Leaf Area with Leaf Area Index (LAI):

   • Shortcut: Multiply the ground area by the leaf area index.

For CBSE Board:

1. Area of a Rectangle (Leaf):

   • Formula: $A = length \times width$

2. Radius of a Circle (Tree Trunk):

   • Formula: $r = circumference \div 2 \pi$. Where $r$ is the radius and circumference is the length of the circumference of the circular trunk.

3. Leaf Area Ratio (LAR):

   • Shortcut: Divide the total leaf area by the height of the plant.

For Additional Numerical Examples:

1. Total Leaf Area with Branches and Leaves:

   • Shortcut: Multiply the number of branches by the number of leaves per branch and then multiply by the leaf area per leaf.

2. Volume of a Cylinder (Tree Trunk):

   • Trick: Consider the trunk as a cylinder and use the formula for the volume of a cylinder: $V = \pi r^2 h$, where $r$ is the radius of the trunk, and $h$ is the height of the trunk.

3. Total Leaf Area with Leaf Area Index (LAI):

   • Shortcut: Multiply the ground area by the leaf area index.
