The base diagonal of the box is just the hypotenuse of a right triangle with legs of 32 in and 8 in
So...its length is just √ [32^2 + 8^2] = 32.98 in
So...this is shorter than the bat
The length of the interior diagonal is just the Pythagorean Theorem "one dimension up" and is equal to
√ [ L^2 + W^2 + H^2 ] = √ [32^2 + 8^2 + 6^2 ] = 33.52 in
This is also shorter than the bat
So....the bat will not fit in the box
