Cuboid enlargement

By how many percent increases the volume of cuboid if its every dimension increases by 30%?

Correct result:

p =  119.7 %

Solution:

a=1 b=1 c=1 V1=a b c=1 1 1=1 k=1+30/100=1310=1.3 V2=k a k b k c=1.3 1 1.3 1 1.3 1=2.197 p=100 (V2V1)/V1=100 (2.1971)/1=119710=119.7=119710%=119.7%   Verifying Solution:  q=k3=1.33=2.197 p2=100 (q1)=100 (2.1971)=119710=119.7 % p2=p
