Subtract all the numbers from 360 and there you go!
The volume for any cube is length x width x height,
so in this case because all side of cube is the same, let it be y.
y x y x y = 27
y = 3
so each side will be 3 inches
N-8=21 should be the answer
Erm 11 isn’t a factor of 64..?
I don't think am right but I hope I can help in any possible way...
3750 for 12 years at 6.5%
multiply 12 * 6.5 = 78% for 12 years
Now we do the following equation -> 3750*0.78 = 2925
Now add 3750 + 2925 = 6675
Hope I'm correct please double check my answer I'm not 100% sure.
Good luck
