FAQs on Mind Map: A Square and A Cube - Mathematics Class 8- New NCERT (Ganita Prakash)

1. What is the difference between a square and a cube in geometry?
Ans. A square is a two-dimensional shape with four equal sides and four right angles, while a cube is a three-dimensional shape with six equal square faces. In simpler terms, a square has length and width, whereas a cube has length, width, and height.
2. How do you calculate the area of a square?
Ans. The area of a square is calculated using the formula A = s², where A is the area and s is the length of one side of the square. For example, if each side of the square is 4 units long, the area would be 4² = 16 square units.
3. What is the formula for finding the volume of a cube?
Ans. The volume of a cube is found using the formula V = s³, where V is the volume and s is the length of one side of the cube. For instance, if a cube has a side length of 3 units, its volume would be 3³ = 27 cubic units.
4. Can you explain the concept of surface area in relation to cubes?
Ans. Surface area refers to the total area of all the surfaces of a three-dimensional shape. For a cube, the surface area can be calculated using the formula SA = 6s², where SA is the surface area and s is the length of one side. Therefore, if a cube has a side length of 2 units, its surface area would be 6(2²) = 24 square units.
5. Why are squares and cubes important in real-life applications?
Ans. Squares and cubes are fundamental in various real-life applications, including architecture, engineering, and design. Squares are used in floor plans and tile designs, while cubes are important in packaging, construction, and 3D modeling, enabling us to create and visualize spaces effectively.
