Question

click on the bubble of the correct answer. to reach an underground methane gas well, workers dig a rectangular trench 6 feet wide, 8 feet long, and 9 feet deep. how many cubic feet of dirt did they remove from the trench? you may select the formula needed to solve this problem from the formula sheet. click on the formula sheet icon to open it. select one: a. 48 b. 144 c. 300 d. 432

Explanation:

Step1: Identify the shape and formula

The trench is a rectangular - prism. The volume formula for a rectangular - prism is $V = l\times w\times h$, where $l$ is length, $w$ is width, and $h$ is height (or depth in this case).

Step2: Substitute the given values

Given $w = 6$ feet, $l = 8$ feet, and $h = 9$ feet. Then $V=8\times6\times9$.

Step3: Calculate the volume

$8\times6 = 48$, and $48\times9=432$ cubic feet.

Answer:

D. 432
