2D Shapes:
- Square: Area (A) = side length (s) ²
- Rectangle: Area (A) = length (l) x width (w)
- Triangle: Area (A) = ½ x base (b) x height (h)
- Circle: Area (A) = π (pi) x radius (r) ²
- Parallelogram: Area (A) = base (b) x height (h)
- Trapezoid: Area (A) = ½ (base1 + base2) x height (h)
3D Shapes:
- Cube: Volume (V) = side length (s) ³
- Cuboid: Volume (V) = length (l) x width (w) x height (h)
- Sphere: Volume (V) = (4/3)π x radius (r) ³
- Cylinder: Volume (V) = π x radius (r) ² x height (h)
- Cone: Volume (V) = (1/3)π x radius (r) ² x height (h)
- Pyramid: Volume (V) = (1/3) x base area (A) x height (h)
Additional Tips:
- π (pi) is a mathematical constant with an approximate value of 3.14159.
- Remember to use consistent units for all measurements (e.g., centimeters, meters, inches) within a calculation.
