Answer:
Yes.
Step-by-step explanation:
If a graph G doesn't have a circuit, we must have that

where
is the number of edges of the graph and
the number of vertices. However, in this case it holds that

The volume of a pyramid is found by multiplying the length, width and height together then dividing by 3.
length x width x height = 12 x 12 x 12 = 1728
volume = 1728 / 3 = 576 cubic cm
The answer to this rests on knowing that there are four properties of multiplication (which your teacher will likely expect you to know...):
These are:
1. commutative
2. associative
3. multiplicative identity
4. distributive
I won't define each of these -- they should be in your notes or textbook. Look them up.
In this case, we are multiplying three terms together -- on the left hand side the parentheses mean to multiply a and b first, then multiply that by 3. On the right hand side, we multiply b times 3 first, and then multiply the product by a.
This would be an example of the associative property of multiplication: when three or more factors are multiplied together, the product is the same regardless of how the factors are grouped.
Hope this helps!
Good luck
