Final answer:
To calculate the dirt removed for the gas well, multiply the trench dimensions (6 ft by 8 ft by 9 ft) to get a volume of 432 cubic feet.
Step-by-step explanation:
The amount of dirt removed from a trench to reach an underground methane gas well can be calculated by finding the volume of the trench. Given the dimensions of the trench are 6 feet wide, 8 feet long, and 9 feet deep, we use the formula for the volume of a rectangular prism, which is length × width × height.
So the volume of dirt removed is 6 ft × 8 ft × 9 ft = 432 cubic feet. This represents the amount of dirt that workers would need to remove to dig the trench to the specified dimensions.
