There are different formulae for different shapes and these vary in complexity.
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.
-1
The rule for S.A = 2bh + 2bw + 2hw
find the area of triangles(reflecting surfaces) and also the area of rectangle or square(base)and find the sum of both.
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?
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 a composite figure, first, break it down into simpler shapes (like rectangles, circles, and triangles) whose surface areas you can calculate easily. Measure the dimensions of each individual shape and apply the appropriate surface area formulas. Once you have the surface areas of the individual components, sum them up, making sure to subtract the areas of any overlapping sections if necessary. Finally, ensure that all measurements are in the same units before adding them together.
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.
Break it down into smaller shapes, find the area of those bits, then add them all together.
To find the surface area of a figure, first identify its shape and calculate the area of each distinct face or surface. For composite shapes, break them down into simpler geometric figures (like rectangles, triangles, or circles), calculate the area for each, and then sum those areas together. If the figure is three-dimensional, use the appropriate formulas for volume and lateral area, ensuring you include all surfaces. Finally, ensure all units are consistent for accurate results.
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.
