This corner unit has a 16cm long straight bit at the back, two angled sides each 54 cm long and a curved front linking the two sides which is around 108cm long. We majored the straight line distance between the two sides as 95cm. We also found the gap between the straight but and the curved frontage maxed out at 19cm.
We then reminded ourselves of a bit of the work of Pythagoras and treated the tank as:
1. two right-angle triangle (taking account of the two sides)
2. a rectangle at the back (the bit between the two triangles)
3. half-a-rectangle at the front taking account of the curved section.
