  Rectangular part is obvious right.

  From bottom of triangle to top of triangle, the width of the triangle increases, hence more time required to fill the prism.

  Assume area of rectangular base = A

  volume of prism = 5A + 5/2A = 7.5A

  Time taken to fill the bottom = 2.5A/7.5A x 6 = 2 mins

  Since the question say sketch, the gradient don't have to be completely accurate (feel free to correct me on this if it's wrong), hence the graph looks like what you see there.. as for the cuboid, constant increase, should be no need explain right
