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

Answer:

405 cubic feet.

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.

$\text{Volume of a cuboid=Length}\times Width\times Depth$

Substitute the given values:

$V=81\times3\times\frac{5}{3}=405\text{ cubic feet}$

The volume of dirt removed was 405 cubic feet.
