20.) What is the volume of the sphere? Round the answer to the nearest cubic unit.
http://assets.openstudy.com/updates/attachments/55bff878e4b03325500374c7lollygirl2171438675119264as.jpg
my answer: 2145 cm^3. Is that correct?
24.) What is the scale factor of a cube with volume 1331 ft^3 to a cube with volume 85184ft^3?
my answer: 4:1. Is that correct?

Best ResponseYou've already chosen the best response.0for second one , take the cube root of each, that will give the side length then the scaling factor is the ratio of linear measurements or ratio of he side measurements....
