When calculating the volume or surface area of a composite solid, split the shape up into sections and calculate each element separately. The front face and the back face are identical.

"The results obtained in our paper are very consistent with the literature, and we hope they will help to improve our understanding of how composite electrolytes can be used for all-solid-state ...

Often volume questions at National 5 involve a composite solid (a solid made up of at least two basic solids). It is possible to calculate the volume of composite solids by simply splitting the ...
