1. ## Easy problem my book dosn't explain.

If R^3 = 351. what is the value of 4r^3.

2. Until they give you some way to relate R and r, there is no way to proceed. Sorry!

3. sorry about the cap and lower case, the R's were the same

If R to the power of 3 = 351
What is the value of 4 times R to the power of 3?

if that explains it better

the answer is 1404, or at least that what the answer key says.
How do they get the answer???

$r^3 = 351$

$4r^3 = 4\times 351$.
