"Apakah kamu tahu bentuk apa ini?"

Translation: Do you know what shape this is?

[mjzeekdaniels]

Is this different from, "Do you know what is this shape"?

[LaszloBoer]

English would be, "Do you know what shape is this?”, and not " ... this is?".

[KamoSaru]

I don't think so. "Do you know what shape this is?" should be correct. Like "Do you know when you come?" and "Do you know who it is?".
