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?
How do you find the area of an composite figure?
Break it down into smaller shapes, find the area of those bits, then add them all together.
Why do you need to know how to find the area of a 2-D figure in order to find the surface area or volume of a 3-D figure?
-1
How do you find the surface area of a figure?
The rule for S.A = 2bh + 2bw + 2hw
How do you figure out the surface area of a triangular prism?
find the area of triangles(reflecting surfaces) and also the area of rectangle or square(base)and find the sum of both.
How do you find the surface are of a composite figure?
Add the areas of all shapes or all faces that make up the composite figure.
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?
How do you find the volume of a composite shape?
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.
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 an composite figure?
Break it down into smaller shapes, find the area of those bits, then add them all together.
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 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.
What is the answer to To find the surface area of a three-dimensional figure you must find the area of each?
... face and add them together.
