To determine the weight of wastewater in a cubic tank with dimensions of 10 feet on each side, we must first calculate the volume of the tank in cubic feet, which is achieved by multiplying the length, width, and height of the tank.

In this case, the volume of the cubic tank is:

\[

\text{Volume} = \text{length} \times \text{width} \times \text{height} = 10 \text{ ft} \times 10 \text{ ft} \times 10 \text{ ft} = 1,000 \text{ cubic feet}

\]

Next, we need to convert this volume into weight. The weight of wastewater can generally be estimated as approximately 62.4 pounds per cubic foot. This figure can vary slightly depending on the composition and temperature of the wastewater, but it is a widely accepted standard for calculations.

Now, we calculate the weight of the wastewater:

\[

\text{Weight} = \text{Volume} \times \text{Weight per cubic foot} = 1,000 \text{ cubic feet} \times 62.4 \text{ lbs/cubic foot} = 62,400 \text{
