It is given that the surface area of cube (S) of a side x⇒ S = 6x2= (12x)Δx= (12x)(0.01x)= 0.12x2Therefore, the approximate change in the surface area of a cube of side x metres caused by decreasing the side by 1% is 0.12x2.

Class 12th NCERT - Mathematics Part-I 6. Application of Derivatives

Answer :

It is given that the surface area of cube (S) of a side x

⇒ S = 6x²

= (12x)Δx

= (12x)(0.01x)

= 0.12x²

Therefore, the approximate change in the surface area of a cube of side x metres caused by decreasing the side by 1% is 0.12x².
