Answer:
surface area decreased by 19%
Explanation:
Let side a=100
Lateral surface area of cube = 4*a^2
=40000
decreased by 10% means
100-10=90
Lateral surface area of cube = 4*a^2
=4*8100
=32400
so surface area decreased
Percentage change =(Difference/small(or)large number)*100
If the number decreased take large number as denominator
If the number increased take small number as denominator
difference is 40000-32400=7600
% change=7600/40000*100
=19%
you can apple for Total surface area also,but result is same
