Question

How is finding the volume of a composite figure like finding the surface area of a composite figure?

A. Both can be found by using a formula that includes the length, width, and height of the figure.

B. Both can be found by finding the total volume of the figure.

C. Both can be found by finding the measure of each figure that makes up the composite figure and then adding the measures.

D. Both can be found by subtracting the measure of one figure from the measure of the other figure.

Answer 1

Answer:

To find the surface area of a composite 3D figure, add the areas of each geometric figure making up the composite 3D figure. To find the volume of a composite 3D figure, draw any necessary planes to view the figure as basic three dimensional figures, then: add basic figure volumes belonging to the composite shape.

Step-by-step explanation:

Answer 2

The volume of a composite figure can be found using C) Both can be found by finding the measure of each figure that makes up the composite figure and then adding the measures.

• Finding the volume of the composite figures are same as finding the surface area of the composite figures.
• Generally, composite figures consist of 2 or more simple figures within them.
• To find the volume of such figures, first, we need to figure out the simple figures that make up the composite figure.
• Then, the volume of each simple figure is to be computed mathematically.
• The final step is to add the volumes of all the simple figures that constituted the composite figure. In this way, the total volume of the composite figure could be easily found.
