Answer:

Let the width be = w

The length will be = w+8

And height = 3 inches

Volume = l x w x h

76=w(w+8)(3)

=> 76=(w^{2}+8w)3

=> 76=3w^{2}+24w

=> 3w^{2}+24w-76=0

Solving this we get w = 2.43 inch or w = -10.43 inch

Neglecting the negative value, we get w = 2.43 inches.

And l=2.43+8=10.43 inches
