Volume is the amount of room inside a 3-dimensional figure. It is measure up in cubic units. A cubic centimeter is a cube the is 1 centimeter wide, 1 cm long, and also 1 centimeter high.

Another method to think that volume is to uncover the variety of unit cubes essential for structure the figure.

 Example 1Suppose this is a cubic unit: How countless cubic systems would be needed to develop this object? Example 2How many unit cubes are required to construct this object? Example 3How many cubes space in this figure? There space 6 cubes top top the bottom "floor" over there are additionally 6 cubes ~ above the 2nd "floor" And there room 6 cubes top top the 3rd (top) "floor"So, there are 18 cubes in this figure.

Example 3 reflects us that a shortcut for recognize the volume that a rectangular prism is to uncover the number of cubes ~ above the bottom "floor" and the main point by the variety of floors.

 Volume = (number of cubes on the bottom floor) x (number the floors) Volume = Area the the base x height Volume = together • w • h

Let"s exercise this shortcut with a couple of more examples...

 Example 4Find the volume the this rectangular prism. Volume = (Area that the base) • (height) Volume = (4 • 3) • 5 Volume = 60 \$\mboxcm^3\$(If you look at each layer, there room 12 cubes in each. There are 5 layers, so that would make a total of 60 cubes.)

 Example 5Find the volume. Volume = together • w • hVolume = 6 • 3 • 3Volume = 36 cubic units

 Example 6Find the volume. V = l • w • hV = 5 • 4 • 7V = 140 devices cubed
