a) surface
b) cube volume
if the edge of the cube increases by 25%?

Correct answer:

p1 =  56.25 %
p2 =  95.3125 %

Step-by-step explanation:

p=25 % q=1+p/100=1+25/100=45=1.25  S0 = 6a2  S1 = 6(qa)2 = 6a2   q2 = S0   q2  p1 = 100   S0S1S0  p1 = 100    S0S0 q2S0  p1=100 (q21)=100 (1.2521)=4225%=56.25%
V0 = a3 V1 = (qa)3 = q3a3 = q3  V0 p2 = 100   V0V1V0 = 100   V0V0 q3V0  p2=100 (q31)=100 (1.2531)=161525%=95.3125%
