A field is 150m long and 100m wide. A plot (outside the field) 50m long and 30m wide is dug to a depth of 8m and the earth taken out from the plot is spread evenly in the field. By how much is the level of field raised?

Explanation

To solve the problem step by step, we will calculate the volume of the earth dug from the plot and then determine how much the level of the field is raised when this earth is spread evenly over the field.

### Step-by-Step Solution:

**Step 1: Calculate the volume of the earth dug from the plot.**

The formula for the volume of a cuboid is:
\[ \text{Volume} = \text{Length} \times \text{Width} \times \text{Height} \]
