b i believe
Step-by-step explanation:
Given that "S" varies inversely as "G", it is an Inverse Variation Relationship. Then, it has this form:

Where "k" is the Constant of Variation.
Knowing that:

When:

You can substitute values and solve for "k":

Then, the equation that models the situation is:

Substituting this value of "G" into the equation and evaluating:

You get:

Hence, the answer is:
The volume is (13ft x 7 ft x 10 ft) cubic feet.
Each of those cubic feet costs $5 .
You should have no trouble with this.
