Unit 6: Mensuration- Mensuration is a branch of mathematics that deals with the measurement of geometric figures like length, area, volume, and other related quantities. It’s an essential topic in mathematics and has numerous practical applications in fields such as engineering, architecture, construction, and various other industries.
The fundamental concepts in mensuration include:
- Length: It refers to the measurement of the distance between two points. Length is usually measured in units like meters (m), centimeters (cm), feet (ft), inches (in), etc.
- Area: Area is the measure of the surface covered by a two-dimensional shape. Common units for measuring area include square meters (m²), square centimeters (cm²), square feet (ft²), etc.
- Volume: Volume is the measure of the amount of space occupied by a three-dimensional object. It is typically expressed in cubic units like cubic meters (m³), cubic centimeters (cm³), cubic feet (ft³), etc.
- Perimeter: Perimeter is the total length of the boundary of a two-dimensional shape, usually measured in the same units as length.
- Surface Area: It refers to the total area of all the surfaces of a three-dimensional shape. Surface area is measured in square units.
- Circumference: Circumference is the distance around the outer boundary of a circle.
- Diagonal: The diagonal is a line segment that connects two non-adjacent vertices in a polygon or a three-dimensional shape.
Various formulas are used to calculate the measurements of different geometric figures. Here are some common formulas used in mensuration:
- Area of a rectangle: A = length × width
- Area of a square: A = side × side (or A = side^2)
- Area of a triangle: A = (base × height) / 2
- Area of a circle: A = π × radius^2 (where π is approximately 3.14159)
- Volume of a cube: V = side × side × side (or V = side^3)
- Volume of a cylinder: V = π × radius^2 × height
- Volume of a sphere: V = (4/3) × π × radius^3
These are just a few examples of formulas used in mensuration. There are many more for different geometric shapes and their measurements.

Case Study on Class 10 Mathematics Unit 6: Mensuration
Applying Class 10 Mathematics Unit 6 – Mensuration in Construction Project
Background: Let’s consider a case study where a construction company is tasked with building a rectangular swimming pool for a residential project. The pool is to be constructed in the backyard of a property and needs to be designed and planned according to specific dimensions provided by the homeowner.
Objective: The objective is to use the concepts of Class 10 Mathematics Unit 6: Mensuration to calculate the required materials, estimate the construction cost, and ensure the pool meets the homeowner’s specifications.
Given Information: The homeowner wants a rectangular pool with the following specifications:
- Length of the pool: 15 meters
- Width of the pool: 6 meters
- Depth of the pool: 1.5 meters
Steps Involved:
- Calculating the Pool Area: Using the formula for the area of a rectangle, we can calculate the area of the pool’s base: Area of Rectangle = Length × Width Area of the pool = 15 meters × 6 meters = 90 square meters
- Finding the Volume of the Pool: The volume of the pool can be calculated using the formula for the volume of a rectangular prism: Volume of Rectangular Prism = Length × Width × Depth Volume of the pool = 15 meters × 6 meters × 1.5 meters = 135 cubic meters
- Estimating the Volume of Water Required: Since the volume of the pool is 135 cubic meters, the pool will require 135,000 liters of water (1 cubic meter = 1,000 liters).
- Determining the Quantity of Concrete: To construct the pool, concrete will be required. Since the pool has a rectangular shape, the amount of concrete needed can be calculated by finding the surface area of the pool walls. Surface Area of the Pool Walls = (2 × Length × Depth) + (2 × Width × Depth) Surface Area of the Pool Walls = (2 × 15 meters × 1.5 meters) + (2 × 6 meters × 1.5 meters) = 45 square meters + 18 square meters = 63 square meters
- Calculating the Cost of Construction: The construction company can now estimate the cost of the project by considering the costs of materials, labor, and other expenses.
Conclusion: Using the concepts from Class 10 Mathematics Unit 6: Mensuration, the construction company was able to calculate the area, volume, and other dimensions required for the swimming pool. The company also estimated the quantity of water needed to fill the pool and the amount of concrete required for construction. This enabled them to plan the project effectively and provide the homeowner with an accurate estimate of the construction cost. By applying mensuration skills, the company successfully completed the construction project meeting the client’s specifications and requirements.
