A composite figure is a figure that is made up of two or more geometric figures.
Composite
TRUE: To find the surface area of a three dimensional figure, you must find the area of each of its faces and then add them together.
you need measurements to figure out surface area. the simplest way to figure out the whole area of a dodecahedron is to find the surface area of one pentagon, then multiply by 12 (the number of sides of a dodecahedron)
