FAQs on Surface Area and Volume of Cube and Cuboid Video Lecture - Mathematics for EmSAT Achieve

1. What is the formula for finding the surface area of a cube?
Ans. The formula for finding the surface area of a cube is 6a^2, where 'a' represents the length of one side of the cube.
2. How do you calculate the volume of a cuboid?
Ans. The volume of a cuboid can be calculated by multiplying its length, width, and height. The formula is V = lwh, where 'l' represents the length, 'w' represents the width, and 'h' represents the height of the cuboid.
3. How do you find the volume of a cube if only the surface area is given?
Ans. If the surface area of a cube is given, the volume can be found by using the formula V = (SA)^2/6, where 'SA' represents the surface area of the cube.
4. Can the surface area of a cuboid ever be equal to its volume?
Ans. No, the surface area of a cuboid can never be equal to its volume. The surface area is always measured in square units, while the volume is measured in cubic units. Hence, they have different dimensions and cannot be equal.
5. How can the surface area and volume of a cube or cuboid be useful in real-life scenarios?
Ans. The surface area and volume calculations are useful in various real-life scenarios. For example, when buying a box or container, knowing the surface area helps determine the amount of material needed to cover it. The volume calculation is useful in determining the capacity of containers or tanks, calculating the amount of liquid or material that can be stored inside.
