1468 is the answer.
You have to find the volume of the large shape and subtract the volume of the small shape. Write the equation as such:
(10*10*15) -(2*4*4)
1500 -32
1468
Well, accordingly to the graph, it has a positive slope so we can eliminate b and d. So it is either a or c. As x increases, so does y. Y is almost not quite equal to 3x-2. In fact, it is greater, so I'd go with A. I'm pretty confident.
I think... 1500
Step-by-step explanation:
multiply 30 and 25 then times 750 as your answer by 2 to get 1500
