The formation of two rectangles is a cube 

two rectangles form a cube. What equation can allow you to find the volume of this cube?

 Super sorry for the bad drawing, one of the answer choices was v=a^3 +b^3, which I don't think makes sense. 

  • What do you mean by two rectangles forming a cube? What are a,b? Please clarify your question.

  • There is not enough information to solve. You are pretty much expecting someone to guess the problem you had seen and solve it.
