Chrome dev tools api: DOM.getBoxModel

I am trying to send model with these parameters :

model:{

content:[0,8,8,8,8,0,0,0],

margin:[0,8,8,8,8,0,0,0],

border:[0,8,8,8,8,0,0,0],

padding:[0,8,8,8,8,0,0,0],

width:8,

height:8

}

but box Model is still not showing in the computed tabs. What could be the reasons and possible solutions? Does anyone know about pageScaleFactor?
