Mark the correct alternative in the following:
If there is an error of a% in measuring the edge of a cube, then percentage error in its surface is:
given that
% Error in measuring the edge of a cube [(ΔL/L)×100] is = a (if L is edge of the cube)
We have to find out (ΔA/A)×100 = ? (IF let the surface of the cube is A)
By the formula of approximation of derivation we get,
=2×a
=2a
