HRESULT GetLevelDesc( UINT Level, D3DSURFACE_DESC * pDesc );
If the method succeeds, the return value is D3D_OK. If the method fails, the return value can be: D3DERR_INVALIDCALL.
The D3DSURFACE_DESC structure contains Width and Height members, which describe the size of one face in the cube. To get the size of the entire cube, multiply six (the number of cube faces) by the product of Width and Height.
