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 20
Find 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.

What is the formula for finding the volume of a composite 3-D shape?
Volume = width x height x length
How do you find the liquid volume of a shape?
Find the circumferrenceThen divide that by the diameterMeasure the shapes' anglesMultiplyThats how you find the liqiud volume of a shape.
How would you find a volume of a regular shape?
If you want to find a volume of a regular shape, You need to multiply Length, Width, and High.
How do you find dimensions from volume?
you look at the shape
How do you find the volume of an irregular shape?
The best way to find the volume of an irregular shape is to split it up into shapes that you know, find the volumes of those individual pieces, and then add up all of the volumes of the split pieces to get your total volume of the irregular shape.
What is the formula to volume of a composite figure?
To find the volume of a composite figure, you would need to break it down into simpler shapes (such as cubes, prisms, cylinders, etc.), calculate the volume of each individual shape using its respective formula, and then add or subtract the volumes of the individual shapes to find the total volume of the composite figure.
How do you find the base of the base shape to find the volume?
You find the length and height of the shape, them you find the volume
How do you find the volume of a shape that has holes?
find the volume of the shape first and then take away the volume of the holes
What is the formula for finding the volume of a composite 3-D shape?
Volume = width x height x length
How do you find the volume of a 2D shape?
The answer is zero. A 2D shape has no volume.
How do you find the liquid volume of a shape?

How do you find the volume of an irregular shape?
The best way to find the volume of an irregular shape is to split it up into shapes that you know, find the volumes of those individual pieces, and then add up all of the volumes of the split pieces to get your total volume of the irregular shape.
How do you find the volume of a composite figure?
You break up the composite figure into smaller shapes whose volumes you can work out, and them add them together.
How do you find the volume of a shape?
You do length times width times height and that is how you get your answer to the volume.
How do find the volume of a polyhedron?
first, find the volume of each shape that is in the polyhedron. then you add all of them together.
