Hello expert and helper

i am having OpenGL exam but i have not understand some last year passpaper question. so will you please help me to answer these question for me so then i can understand bit more. thank you advance.

the questions are below, please answer any question that you know.

1.) A Cube is defined as a series of 8 vertices and six facets on a coordinate system whose origin is at the centre of the cube. A cube can be used to define the buildings on the street. several instances of the cube model will be used to generate the following buildings.

a.) A hight rise block of flats of width = 1 unit, height = 10 units, depth = 1 unit.

b.) A department store of width = 4 units, height= 2 units, depth = 1 unit.

c.) A small house of width = 1 unit, height = 1.5 units, depth = 1.5 units.

what matrices would be used to scale the cube so as to create instances of the buildings suggested above?

(10 marks Worth Question)

2.) What technique could be used to give the cuboids described in the above question the appearance of real buildings?

(10 marks Worth Question)

3.) Outline the file reading process by which

*) a binary format file defining a model is read

**) and its details is stored in a data structure designed to accommodate a collection of geometric objects possibly connected and possibly textured.

(10 marks Worth Question)

please answer the question to help me to revise this sample exam question. thank you again.

PS: Problem is our uni is in holiday and my teacher wont be answer my emails. i try to contact them past few days but they are not responding. therefore, i am asking here that some one could help me because i am running out of my time for the exam.
