The length, width and height of the smaller box are n inches , n inches and 8 inches respectively,
And, According to the question,
The shipping boxes has 2 inches extra width than that of smaller box and 4 inches extra length than that of smaller box, Also, The height of the shipping box should be the same as the helmet box.
Thus, the Length of the shipping box = (n + 4) inches
Width = (n+2) inches and height = 8 inches
Thus, the volume of the shipping box,
But, V = 1,144 cubic inches,
