Question

a rectangular plot of land measures 12 metre by 15 metre update 8 by 6 metre by 50 cm in the field and the soil removed is spread evenly over the remaining portion of the field find the increase in the level of the remaining portion of the field​

Answer 1

Answer:

Dimensions of the field = 15 m × 12 m

Dimensions of the pit = 8 m × 2.5m × 2m

Volume of earth removed from the pit = 8m × 2.5 m × 2 m = 40 m³

Area of the remaining field

= Area of the field – Area of the pit

= (15 m × 12 m) – (8 m × 2.5 m)

= 160 m²

Since, the earth removed is evenly spread over the remaining area of the field.

∴ Increase in level of remaining field × Area of remaining field  = Volume of earth removed from the pit.

Increase in level of remaining field = 40/160 =0.25m
