Answer 1

Step-by-step explanation:

Given The length and breadth of a rectangular field of the village are 20 m. and 15 m. respectively For construction of pillars in the 4 corners of that field 4 cubic holes having length of 4 m. are dug out and the soils removed are dispersed on the remaining land. Let us calculate and write the height of the surfaces of the field that is increased by

• So length of the rectangular field = 20 m
• Breadth of the rectangular field = 15 m
• Corners of each cubic hole = 4m
• So total number of cubic holes = 4
• Now volume of soil deposited on the rectangular field = total volume of soil taken out of 4 cubical holes.
• So we have
•             20 x 15 x h = 4 x 4 cube
•                300 h = 4 x 4^3
•                300 h = 256
•                 Or h = 256 / 300
•               Or h = 0.853 m
