The measurement of area, perimeter, and volume is crucial to construction projects, crafts, and other applications. Area is the space inside the boundary of a two-dimensional shape. Perimeter is the distance around a two-dimensional shape such as a square or circle. Volume is a measure of the three-dimensional space taken up by an object, such as a cube. If you know the object's dimensions, then measurement of area and volume is easy. Surface area and volume formulas for all everyday geometric shapes can easily be found online, although it's not a bad idea to review how to derive these on your own should the need arise. You can also often get one of these from another; for example, if you know the formula for the area of a circle, you may be able to figure out that the volume of a cylinder is just the area of the associated circle(s) at the end times the cylinder's height.
