Your job is to determine the coordinates of the remaining corners of the building; the side length of the cube; the lengths of the four segments AA', BB', CC', DD'; the area of the quadrilateral A'B'C' D': and, finally, the volume of the part of the cube that sits above the ground.

Question

Hi there, i need some help in finding the A' and C' coordinates. Also i have found D' to be (28.452,10.8853,0) if that helps.

Modelling our 5 x 5 x 5 Rubik's cube
The following pictures show a curious Rubik's-cube-like structure that greets visitors to the Melbourne
Museum.
A.
West
A'
The picture on the right shows what you see when you look at the cube from above using Google Earth
Google Earth allows you to view many prominent buildings in 3D. Imagine that you are the maths wiz at
Google whose job it is to create a 3D image of our cube for Google Earth. This means that you have to
find coordinates of the corners of the square A, B, C, D visible from the top, as well as the coordinates
of the points A', B', C', D' at which four edges of the cube intersect the ground. As indicated in the
picture on the left, A is supposed to be connected to A' by such an edge, and similarly for B and B', C
and C', and D and D'.
It is your first day on the job and you are supposed to base your work on that of your predecessor, who
got fired yesterday. Their notes are a terrible mess, but it is clear that they started modelling the cube
by letting the (flat) ground coincide with the ry-plane and having the r-axis point North and the y-axis
point West. Their notes don't tell you where the origin of the coordinate system is supposed to be, but
wherever it may be, in this coordinate system we have
B (1.9651, 19.8699, 0),
D=(29.2866, 13.3456, 11.9406).
B= (2.7997, 22.3302, 11.9406),

For any single one of these vectors/values that you get wrong, 1 mark1 will be deducted. One
mistake that implies other mistakes will result in every single one of these mistakes being penalised
in this way - Google Earth only accepts results that work! Please make absolutely sure that you
double-check your results before you submit your report!
