Answer :

To determine the total weight of 9.4 gallons of water, follow this step-by-step process:

1. Identify the weight of water per gallon:
Water weighs 8.355 pounds per gallon.

2. Identify the number of gallons:
We have 9.4 gallons of water.

3. Calculate the total weight:
Multiply the weight of each gallon by the number of gallons:

[tex]\[ \text{Total weight} = (\text{Weight per gallon}) \times (\text{Number of gallons}) \][/tex]

[tex]\[ \text{Total weight} = 8.355 \, \text{pounds/gallon} \times 9.4 \, \text{gallons} \][/tex]

4. Perform the multiplication:
When you multiply 8.355 by 9.4, you obtain the total weight.

The total weight of 9.4 gallons of water is:

[tex]\[ 78.537 \, \text{pounds} \][/tex]

So, 9.4 gallons of water weigh 78.537 pounds.
