svg exported from 3d image loses a piece when viewed in wordpress

Hi eveyone,

I created a 3d figure, a cube and covered its faces with a texture, if this is the correct term. 

The problem:
The image is exported as svg. Apparently the display of the image is consistent with expectations, but when I load it on the website I'm building (wordpress + Oxygen Builder in localhost), the image is not displayed 100%. A piece is missing.

Notes from non-expert user
When I select the image in Illustrator, a bounding box appears above the cube that does not span 100% of the cube. The side that remains outside the selection rectangle corresponds to the portion of the image that I cannot see in WordPress.

The image opened by the browser can be seen at 100%, but if I resize the window manually the image is not responsive, however if I select different viewpoints via an extension, the image is responsive.
Last detail, the preview from Win's file explorer shows the same problem of cropping the image in correspondence with the portion not covered by the selection box.

My hypotheses to solve the problem
The bounding box must span the extent of the cube, but how do I achieve this?

Thank you very match

Arturo
