The block has 10 cm, 20 cm, and 50 cm dimensions. We reduce the first edge of the cuboid by 20% and increase the second by 20%. How does the volume of the cuboid change? By how many percent?

Correct answer:

p =  -4 %

Step-by-step explanation:

a=10 cm b=20 cm c=50 cm  V1=a b c=10 20 50=10000 cm3  r1=100%20%=110020=0.8 r2=100%+20%=1+10020=1.2  A=r1 a=0.8 10=8 cm B=r2 b=1.2 20=24 cm C=c=50 cm  V2=A B C=8 24 50=9600 cm3  p=V1V2V1 100=10000960010000 100=4%
