Solution

Let us assume the left vertical line as y axis, and horizontal as x axis

delta x = h = 50 cm each.

Left bottom end is origin (0,0)

If we consider the 8 rectangles approximately formed by partititions of 50 cm each, each rectangle according to left sum has height

Thickness = depth = 0.06 m

Hence volume = 9250000(0.06)

= 555000 m^3

x	0	50	100	150	200	250	300	350
L of rectangle	0	130	120	130	440	140	80	0
Total L of rectangle	0	6500	12000	19500	88000	35000	24000		185000
Width									50
		Total area according to Left sum				9250000
