Question

A pipe trench is roughly rectangular with dimensions 81 feet long by 3 feet wide and with an average depth of 1 2/3 feet. What volume of dirt was removed?

Answer 1

405 cubic feet.

Step-by-step explanation:

The dimensions of the rectangular trench are given below:

• Length = 81 feet

,

• Width = 3 feet

,

• Depth = 1 2/3 = 5/3 feet

To calculate the volume of dirt that was removed, we will need to find the volume of the cuboid-shaped trench.

`\text{Volume of a cuboid=Length}* Width* Depth`

Substitute the given values:

`V=81*3*(5)/(3)=405\text{ cubic feet}`

The volume of dirt removed was 405 cubic feet.
