Please answer it and explain.

Its times 2 of the one on the left.

So the polygon PQRST is multiplied by a scale factor of 2. So it basically is doubled in size. We know this because on the graph paper we see that the line CD was once 2 spaces wide and now on the new polygon (line RS) it is 4 spaces wide. I hope this helps!

468

Step-by-step explanation:

The volume of a cube is V = s³. Fin the volume of each cube separately and add together for the volume all together.

The small cube has side length 5 so V = 5³ = 125.

The large cube has side length 7 since 12 - 5 = 7. So V = 7³ = 343.

Together the volume is 125 + 343 = 468
