Adjusting height of embedded object malfunctioning

Hi,

I'm trying to adjust the height of an embedded Google Doc -- basically trying to not have people scroll through it. But, when I add any height="_____px" to the iframe code it adds a LOT of white space to the bottom of the doc. Any finagling of the actual number doesn't change it.

Here is the code I'm using:

<iframe src="https://docs.google.com/document/d/e/2PACX-1vRLMtqctmue4tBR5jqytjT6G4Vh0W-lCwW7rnV8HRSUiX9Qayh6Mu-TQjUmZ3FpO78uYHriP37sFV7U/pub?embedded=true" height="700px"></iframe>

Any help would be much appreciated!
