Key concepts: Mensuration (Class 8 Mathematics)
This chapter covers the area of plane figures (trapezium, quadrilateral, polygon) and the surface area and volume of solids (cuboid, cube, cylinder).
- Area of a trapezium
- Area = ½ × (sum of parallel sides) × height.
- Area of quadrilateral/polygon
- Found by splitting the figure into triangles using a diagonal and adding their areas.
- Surface area
- The total area of all faces of a solid; lateral surface area excludes the top and bottom.
- Volume
- The space occupied by a solid, measured in cubic units; 1 m³ = 1000 L.
- Solids covered
- Cuboid, cube and cylinder — each with its own surface-area and volume formula.
Key formulas — Mensuration
💡 Exam tips for Mensuration
- Match units: convert all measurements to the same unit before computing area or volume.
- Remember 1 cm³ = 1 mL and 1 m³ = 1000 L for capacity conversions.
