Answer:
it is 25
Explanation:
Given:
Dimension of the tank = 30 m × 20 m × 12 m
Dimension of the rectangular field = 588 m × 50 m
Formula used:
Volume of a cuboid = l × b × h
l = length; b = width; h = height
Calculation:
Volume of the sand dug out = 30 m × 20 m × 12 m = 7200 m3
Area of the remaining field(not dug) = (588 × 50) - (30 × 20) = 28800 m2
Height of the field raised = 7200/28800 = 0.25 m
∴ Height of the field raised by it is 25 cm
