Area refers to the space inside a two-dimensional object, like a square or an octagon, while volume refers to the space that a three-dimensional object takes up, or the internal capacity of that object. Units of area inc... More »

A cube is a six-faced, three-dimensional figure composed of square-shaped faces of the same size that meet at 90-degree angles, whereas a cuboid is a box-shaped object made of six faces that all meet at 90-degree angles.... More »

Two-dimensional shapes have dimensions, such as length and width, while three-dimensional shapes have an additional dimension, such as height. Any shape that only has a surface area is a 2-D shape while shapes with volum... More »

The amount of space an object occupies is its volume. Volume is not always a fixed measurement. For any given object, volume is likely varies depending on pressure and temperature. More »

The mass of an object is the amount of matter it contains while volume is the amount of space it takes up. Mass should not be confused with weight, which is the measure of the gravitational force on an object. More »

Fan size is expressed as CFM capacity and is determined by dividing the area of a room by the number of minutes per hour needed to replace the volume of air. CFM indicates cubic feet per minute and indicates the amount o... More »

In math, volume is the amount of space inside a three-dimensional object, or its capacity. A measurement of volume offers insight into how much liquid or how many physical objects a person can fit into an object. Knowing... More »
