anonymous one year ago (Medal and Fan Given) ! If the volume for 3-D polyhedra A is 300 cm3 and the volume for 3-D polyhedral B is 900 cm3. How many times bigger is the volume of pyramid B than pyramid A?

You can solve this by using a proportion because it is asking for the percent. $\frac{ 300 }{ 900 }=\frac{ x }{ 100 }$ If you cross multiply, you will get, $30000=900x$ Now, you can solve for x. You will have to round your answer.
