Mensuration

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

• Area of Rhombus = $\frac{1}{2} \times d<em>1 \times d</em>2$

• Area of General Quadrilateral = $\frac{1}{2} \times d \times (h<em>1 + h</em>2)$

• 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 = $\pi r^2h$
