Question

If the volume for 3-D polyhedra A is 200 cm3 and the volume for 3-D polyhedral B is 800 cm3, what is the percent of change from A to B?

0.4%

4%

40%

400%

Answer 1

@fwizbang

Answer 2

I would say b

Answer 3

First calculate the change. If the volume went from 200 to 800, what was the change?

Answer 4

600

Answer 5

So 600/original amount = 600/200=3 = 300%

Answer 6

I think what they're asking for here is What percent of Vol A is Vol B? In which vase the answer is

100 x Vol B/ Vol A (remember to multiply by 100 to get % )

The percentage change, on the other hand, is

100 x ( Vol B - Vol A)/ Vol A =300%

so the "real" answer is none of the above.

Answer 7

which answer should i pick then

Answer 17

You might want to ask your teacher if the problem is worded correctly.....

Answer 18

It's worded correctly; I have the same problem. And the answer is 400%, because 100% of 200 is 200 so that times 4 (or 400%) is 800.
