Answer 1

Answer:

To find volume multiply length breadth and depth. Then multiply it with 1200

Answer 2

Given - Dimensions of pit = 4m length, 3.5m breadth and 21.5 m depth.

Cost to remove one cubic meter of soil is Rs 1200.

Find - Expenses and volume of soil

Solution - Volume of the compost pit can be calculated by multiplying length, breadth and depth of the pit.

Volume = length*breadth*depth

Volume = 301 metre³

Thus, the volume of soil to be removed from the pit is 301 metre³.

Now, cost to remove one cubic meter of soil is Rs 1200

So cost to remove 301 metre³ of soil = 1200*301

Cost to remove 301 metre³ of soil = Rupees 361200

Thus, the expense is Rupees 361200
