Frequently Asked Questions
What is surface area?
Surface area is the total area of all the external surfaces of a three-dimensional object. It represents how much material would be needed to cover the entire object, and is measured in square units (e.g., square meters, square feet).
How do you calculate the surface area of a sphere?
The surface area of a sphere is calculated using the formula: Surface Area = 4 × π × r², where r is the radius of the sphere and π (pi) is approximately 3.14159.
What's the difference between surface area and volume?
Surface area measures the total area of all external surfaces of an object (in square units), while volume measures the amount of space occupied by the object (in cubic units). Surface area is two-dimensional, while volume is three-dimensional.
