3.2 The total outside height of the bookshelf is 31,496 inches.
Determine (rounded to TWO decimal places) the conversion factor for the height in the form 1 inch = ... cm.
3.3 Tsidi bought the bookshelf at a discounted price because the backboard which covers the entire width and height of the bookshelf, needed painting. She decides to do the following:

  • Remove the backboard.
  • Paint the back of the backboard with a single coat of paint.

3.3.4 Tsidi stated that one 500 ml can of paint is sufficient to paint the backboard completely.
Verify, with calculations, whether her statement is valid.
3.4 Tsidi wants to organise her documents in files. She was informed that you can store files separately (single files) or in a filing box as shown in the picture below.

A single file has a width of 8,1 cm.
The width of the filing box is 345 mm

Use the information above to answer the following questions.
3.4.1 Determine the maximum number of filing boxes that could fit on one shelf, which is 162 cm wide.
3.4.2 Calculate the difference in the number of files that she can place on one shelf if she packs the shelf with single files rather than the filing boxes.
3.4.3 Give a possible reason why Tsidi would prefer the filing boxes.
3.4.4 Tsidi bought filing boxes to pack the top shelf completely. She could not remember in which file she placed a document. She randomly chooses one of the files out of the filing boxes. Determine, as a percentage to TWO decimal places, the probability that the file she chooses will contain the document she is looking for.
