Composite solids are just a combination of simpler solids in disguise.
To find the volume of composite solids such as these:
The exception to these steps is when the solid we are looking at is more simply considered as a larger solid with a smaller solid cut out of it, like these ones.
In this case we would
We can do this because of the volume addition postulate. In the same way that pieces always add up to the whole for segments, angles, and areas, the same is true for volumes.
Volume addition postulate - The volume of a solid is the sum of the volume of all of its non-overlapping parts.
Find the volume of the figure shown, correct to two decimal places.
Use volume formulas for cylinders, pyramids, cones, spheres and composite figures to solve problems.
