Best Answer

To find the area, first divide the shape into regular, simple shapes. Then use formulas to find the area of the smaller, regular shapes. Lastly, add up all the smaller areas to find the area of the original shape.

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 get the area by using formulas. There is usually a specific formula to find the area of each shape. Some irregular shaps may not have a formula.

You find the surface area of a cube by using the formula 6e2. In this case, e=edge.

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.

Yes by working out individual sections and then adding them altogether.
