Area & Volume Formulas — Class 8 ICSE

Calculate area of trapeziums, polygons, and volume of cubes, cuboids, and cylinders.

Key Formulas

Area of Trapezium

A = \dfrac{1}{2}(a + b) \times h

Area of Rhombus

A = \dfrac{1}{2} d_1 \times d_2

Volume of Cube

V = a^3

TSA of Cube

\text{TSA} = 6a^2

Volume of Cuboid

V = l \times b \times h

TSA of Cuboid

\text{TSA} = 2(lb + bh + hl)

Volume of Cylinder

V = \pi r^2 h

TSA of Cylinder

\text{TSA} = 2\pi r(r + h)

Worked Examples
