What is the internal volume of a subwoofer enclosure with dimensions of H= 18.5", W= 15", and D= 27" using 3/4" thick material?

To determine the internal volume of a subwoofer enclosure given the exterior dimensions and the thickness of the material, it's essential to first calculate the internal dimensions by accounting for the thickness of the material on each side of the enclosure.

In this case, the exterior dimensions are:

• Height (H) = 18.5 inches

• Width (W) = 15 inches

• Depth (D) = 27 inches

Since the material is 3/4" thick, it will affect the internal dimensions as follows:

1. For height, the material thickness will reduce the total height twice (once for the top and once for the bottom). So the internal height will be:

Internal Height = H - (2 * 0.75") = 18.5" - 1.5" = 17.0"

2. For width, applying the same logic:

Internal Width = W - (2 * 0.75") = 15" - 1.5" = 13.5"

3. Lastly, for depth:

Internal Depth = D - (2 * 0.75") = 27" - 1.5" = 25.5"

Now, to find
