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
