SVG viewbox hides svg file image

I have inline svg on my site (the svg is designed inline with the html) and the code is in a viewBox. It works perfectly, and it's responsive.

On another page I have an embedded svg image from an svg file (not designed inline with the html). I put it in a viewBox to make it responsive, but now the image doesn't show.

Here's the code:

<svg viewBox="0 0 425 280" xmlns="">
<object type="image/svg+xml" data="images/Embedded SVG Image.svg
">Your browser does not support SVG</object></svg>

The image is 425x280 pixels. If I made the height and width values larger, the SVG still doesn't show.

How can I specify the viewBox so the image shows?
