A figure (or shape) that can be divided into more than one of the basic figures is said to be a composite figure (or shape).For example, figure ABCD is a composite figure as it consists of two basic figures. That is, a figure is formed by a rectangle and triangle as shown below.The area of a composite figure is calculated by dividing the composite figure into basic figures and then using the relevant area formula for each basic figure.Example 20Find the area of the following composite figure:Solution:The figure can be divided into a rectangle and triangle as shown below.So, the area of the composite figure is 216 cm2.
NO. This is the way to get the volume of a prism, not the surface area of any three-dimensional figure. To find the surface area of a three-dimensional figure, you must find the area of each of its faces and then add the side-areas together.
You find the surface area of a cube by using the formula 6e2. In this case, e=edge.
SA = 2lw+2lh+2wh
K, well there is no surface area of a triangle, because a triangle is a 2s figure. Surface area is for a 3d figure. To find the regular area of a triangle the formula is 1/2 of the base X the height :) gl :P
There are different formulae for different shapes and these vary in complexity.
Add the areas of all shapes or all faces that make up the composite figure.
The surface area of a space figure is the total area of all the faces of the figure
You need to find the area of each two dimensional surface on the figure. Do you have a specific figure in mind?

Break it down into smaller shapes, find the area of those bits, then add them all 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)
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.
2*area of triangular faces + perimeter of triangle*length of prism (not prisim).
False.To find the surface area of a three-dimensional figure, find the area of the faces and add them together.
