You!

jing yi is sculpting a small pyramid as a model for a larger pyramid that will be used as a stage prop. the model pyramid has a square base that measures 15 cm on each side. the pyramid has a height of 12 cm.
3a. how much plaster does she need to make the smaller scale model? show your work, and include the units in your answer. (2 points)

3b. the actual stage prop will have a base that is 3 times as long and 3 times as wide, and it will stand 3 times taller. how much plaster does she need to make the actual stage prop? show your work, and include the units in your answer. (2 points)

3c. how many times the volume does the actual stage prop have than the scale model? (hint: either divide the volume of the actual prop by the volume of the scale model, or apply the relevant theorem.) (1 points)

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:
