Mensuration

• Area of Trapezium = \frac{1}{2} \times (a + b) \times h

• Area of Rhombus = \frac{1}{2} \times d1 \times d2

• Area of General Quadrilateral = \frac{1}{2} \times d \times (h1 + h2)

• Lateral Surface Area of Cuboid = 2h(l + b)

• Total Surface Area of Cuboid = 2(lb + bh + hl)

• Volume of Cuboid = l \times b \times h

• Lateral Surface Area of Cube = 4a^2

• Total Surface Area of Cube = 6a^2

• Volume of Cube = a^3

• Curved Surface Area of Cylinder = 2\pi rh

• Total Surface Area of Cylinder = 2\pi r(r + h)

• Volume of Cylinder = \pi r^2h
