Since Volume (V) = 
……….(i)
……….(ii)
It is given that increase in side = 1% = 
……….(iii)
Since approximate change in volume V of cube = 
= 
= 
cubic meters
Find the approximate change in the volume V of a cube of side x metres caused by increasing the side by 1%.
Find the approximate change in the volume V of a cube of side x metres caused by increasing the side by 1%.
