Josh and Jonah were finding the volume of the prism below.
• Josh say that he can see on the end of the prism that each layer will have 16 cubes in it.
• Jonah says that each layer from top to bottom has 24 cubes in it.
Who is right? In the space provided, explain how you know using words, numbers, and/or pictures.
What is the total volume of the rectangular prism?

1. to rewrite as a fraction of h f (h) , write the equation so that p is by itself on one side of the equal sign and an expression involving only j is on the other side .f (h) = 7.5h 2. solve for p by simplifying both sides of the equation , then isolating the variable .p = 0.13h3. write a function of p f (p) = p/154. f (p) = -15 + p
