Surface area is the total area that the surface of a three-dimensional object occupies. It is a measure of how much exposed area a solid object has and is typically expressed in square units (e.g., square meters, square centimeters). The calculation of surface area varies depending on the shape of the object.
For example:
- For a cube, the surface area \(A\) is calculated using the formula \(A = 6s^2\), where \(s\) is the length of a side.
- For a rectangular prism, the surface area is given by \(A = 2(lb + lh + wh)\), where \(l\), \(w\), and \(h\) are the length, width, and height, respectively.
- For a sphere, the surface area is calculated as \(A = 4\pi r^2\), where \(r\) is the radius.
Surface area is important in various fields, including physics, engineering, and architecture, as it can impact phenomena such as heat transfer, chemical reactions, and overall design.
