I have a surface area question for two rectangular cubes (labeled I and II). I know to use Ph but my teacher wrote S= SAI + SAII = Ph + [Ph +2B] and I am confused if these are the Ph for only one cube and what the 2B is. I can send specific question if that helps.

The sat and act tests use very different grading scales. the sat math scores follow a normal distribution with mean 518 and standard deviation of 118. the act math scores follow a normal distribution with mean 20.7 and standard deviation of 5. suppose regan scores a 754 on the math portion of the sat. how much would her sister veronica need to score on the math portion of the act to meet or beat regan's score?
