Case Study Question Mathematics Class 8 on Squares and Roots

Case Study Question Mathematics Class 8 on Squares and Roots focus on understanding perfect squares and square roots through concept-based examples. Students also relate these to Case Study math questions for class 9 and math case study questions class 9 for deeper practice. Through logical steps, learners master factorization and estimation easily. Moreover, they develop critical thinking skills for future exams.

Practice and Learning Benefits

Solving math case study questions helps students strengthen fundamentals and improve speed. Since the problems are practical, they make learning interactive. Therefore, students enjoy studying while improving analytical skills. Additionally, transition to higher classes becomes smooth. So, students can connect their knowledge with real-life examples and perform better in tests.

Mathematics Case Study – Area and Volume

Case Study 1: Estimating the Area and Volume Using Squares and Cubes

Ravi is helping his father design a new square-shaped garden in their backyard. The garden will have a small water tank at the center that is in the shape of a cube. The side of the garden is 36 meters, and Ravi plans to plant grass on the remaining area after constructing the tank. The water tank will have an internal side length of 3 meters. To calculate the cost of planting the grass, Ravi first needs to know the area of the garden and the area occupied by the tank. Additionally, he wishes to know how much water the tank can hold in cubic meters. While performing these calculations, he realizes the importance of understanding squares, square roots, cubes, and cube roots in practical life — especially when dealing with construction, land measurement, and material estimation. Based on this situation, answer the following questions:

1. What is the total area of the square garden?
Solution:
Area of a square = side² = 36² = 1296 m².
2. What is the volume of the cubic water tank?
Solution:
Volume of a cube = side³ = 3³ = 27 m³.
3. How much area of the garden will be used for planting grass (excluding the tank area)?
Solution:
Area for grass = Total area – Tank area = 1296 – 9 = 1287 m². Since the closest correct option is not listed, the correct answer should be 1287 m². So, the correct answer should be updated accordingly.
4. If Ravi decides to make the garden’s side twice as long, what will be the new area?
Solution:
New side = 2 × 36 = 72 m. New area = 72² = 5184 m².
5. The ratio of the area of the garden to the area of the tank is:
Solution:
Area of garden : Area of tank = 36² : 3² = 1296 : 9 = 144 : 1.
