Answer 2

Answer:

  B.  No, Danielle needs to remove 1 rectangle from the ramp and 1 rectangle from the block.

Step-by-step explanation:

It is true that the ramp has 2 triangular and 3 rectangular surfaces, and the block has 6 rectangular surfaces. However, Danielle doesn't want to paint the bottom rectangular surface of either the ramp or the block, so needs to remove one rectangle from each for her area computation.
