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.

To find the surface area of the three dimensional figure you must find the perimeter of a face and then multiply by the height?
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.
How do you find the area of a polygon figure?
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.
How do you figure the surface area of a cube?
You find the surface area of a cube by using the formula 6e2. In this case, e=edge.
How do you figure out area?
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.
How do you find the surface area of a figure if you know the volume of it and a figure similar to it?
SA = 2lw+2lh+2wh
How do you find the surface area of a space figure?
The surface area of a space figure is the total area of all the faces of the figure
To find the surface area of a three dimensional figure what do you have to find?
You need to find the area of each two dimensional surface on the figure. Do you have a specific figure in mind?
When do you find an area or a volume by separating the figure into smaller figure?
when its a irregular shape you divide it up
How do you find the perimeter and area of a irregular figure?
Divide the irregular figure into manageable pieces and work out their individual areas, sum the areas to that of the original figure. Measure the perimeter.
To find the surface area of the three dimensional figure you must find the perimeter of a face and then multiply by the height?
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.
How do you figure out the area of a closed figure?
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.
What is the surface area of a dodecehedron?
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)
Is it true that 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?
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.
How do you find surface area of a triangular prisim?
2*area of triangular faces + perimeter of triangle*length of prism (not prisim).
Is it true that to find the surface area of a three dimensional figure you must find the area of each of its faces and then multiply them together?
False.To find the surface area of a three-dimensional figure, find the area of the faces and add them together.
How do you find the area of a polygon figure?

If perimetre of an irregular figure is known can you find its area?
Yes by working out individual sections and then adding them altogether.
