Answer 1

Answer:

PLZ MARK AS BRAINLY

Step-by-step explanation:

The increase in the level of soil in the remaining portion of the field will be 0.182 meters.

Step-by-step explanation:

The area of the rectangular plot of field measure 12 m by 15 m is (12 × 15) = 180 square meters.

Now, a pit 8 m by 6 m by 50 cm is dug in field and soil removed is spread evenly over the remaining portion of the field.

Now, the area of the field excluding the pit is [180 - (8 × 6)] = 132 square meters.

Now, the volume of soil removed from the pit is (8 × 6 × 0.5) = 24 cubic meters.

Therefore, if the soil thickness throughout the entire plot excluding the pit is x meters, then we can write  

132x = 24

⇒ x = 0.182 meters  

Therefore, the increase in the level of soil in the remaining portion of the field will be 0.182 meters. (Answer)
