Exercise 1
In each of the three coordinate planes (xy, xz, yz) construct a square with a side length 15 whose edges lie on the positive sides of the coordinate axes.
Color these squares in red, blue and green.
Construct a cube for which the constructed squares are faces, and translate it for the vector a = -20i-20j-5k.
Upper face of the cube color red, front face blue, and right face green.
Drawn objects show in the top, front, right view and axonometry.
