Hello Marie,

V(B)/V(A)=900/300=3=300/100=300%

Answer:

c. 300%

Step-by-step explanation:

In order to solve this problem you just have to divide the bigger polyhedral by the smaller polyhedral:

\(\frac{900 cm^{3} }{300cm^{3}}\)

As this is equal to 3, you know that the bigger polyhedral is 3 times bigger than the smaller polyhedral so now you just make a rule of three, if an object that is 100% bigger than other is 1 time bigger, what would be the percentage of an object that is 3 times bigger?

\(\frac{1}{100}=\frac{3}{x}\)

Once you clear the X the equation would look like this:

\(x=\frac{3*100}{1}\)

\(x=300\)
