   What is surface area?

   • Surface area is the total amount of space that all of the surfaces of an object take up. It is the sum of the area of all the surfaces of that object. Finding the surface area of a three-dimensional shape is moderately easy as long as you know the correct formula.

   What is the surface area of a figure?

   • The surface area of a figure (in square units) is the number of unit squares it takes to cover the entire surface without gaps or overlaps. If a three-dimensional figure has flat sides, the sides are called faces. The surface area is the total of the areas of the faces. For example, a rectangular prism has six faces.

   What is a mathematical definition of area?

   • While the areas of many simple surfaces have been known since antiquity, a rigorous mathematical definition of area requires a great deal of care. This should provide a function which assigns a positive real number to a certain class of surfaces that satisfies several natural requirements.

   Mar 27, 2022 · Definition: Surface Area. The surface area of a polyhedron is the number of square units that covers all the faces of the polyhedron, without any gaps or overlaps. For example, if the faces of a cube each have an area of 9 cm 2, then the surface area of the cube is \(6\cdot 9\), or 54 cm 2.
