A rectangular ground reservoir measures 8m long, 6m wide, and 8m deep. What is the total cost of excavation if labor costs P50.00 per cubic meter?

To determine the total cost of excavation for the rectangular ground reservoir, you first need to calculate the volume of the excavation required. The volume of a rectangular prism, such as this reservoir, is calculated using the formula:

Volume = length × width × depth

In this case, the reservoir measures 8 meters long, 6 meters wide, and 8 meters deep. By plugging in these values, you calculate:

Volume = 8m × 6m × 8m = 384 cubic meters.

Next, to find the total cost of excavation, you multiply the volume by the labor cost per cubic meter. With a labor cost of P50.00 for every cubic meter of excavation, the calculation will be:

Total Cost = Volume × Cost per cubic meter

Total Cost = 384 cubic meters × P50.00/cubic meter = P19,200.

This process leads to the conclusion that the total cost of excavation is P19,200, confirming the correctness of the chosen answer.
