Answer:
27 units
Explanation:
If we say the cube is broken up into smaller cubes, volume is the number of tiny cubes total.
An easier way to do this is to remember that the volume equation is V=L*w*h= length*width*height, where the width is 3 cube units, the height is 3 cube units, and the length is 3 cube units. So:
V=3*3*3= 27
If this does not make sense, here is another way to think about volume.
First, lets determine what the area of one surface of the cube is. Area is length times width, so the answer is 9. We can also count the number of cubes, if that is easier.
So we found the area of one face. Now we need to know how many of these square areas makes up the cube. That is, how many 3 by squares will make the cube? From the diagram, we see that there are three cube units across, and if each face area has a width of one cube, then we multiply.
3*9= 27
