A tank contains 643.18 gallons of water. With the weight of water being 8.34 lbs per gallon, how much does the water add to the weight of the tank? Round your answer to two decimal places.

Select one:
A. 4635.12 lbs.
B. 5364.12 lbs.
C. 3897.12 lbs.
D. 4886.12 lbs.
E. 4653.12 lbs.



Answer :

To determine how much weight the water adds to the tank, we'll follow these steps:

1. Identify the tank's capacity in gallons and the weight per gallon of water:
- Tank capacity: 643.18 gallons
- Weight per gallon of water: 8.34 lbs/gallon

2. Calculate the total weight of the water:
- The total weight can be found by multiplying the tank's capacity by the weight of one gallon of water.

[tex]\[ \text{Total Weight} = \text{Tank Capacity} \times \text{Weight per Gallon} \][/tex]

Substituting the given values:

[tex]\[ \text{Total Weight} = 643.18 \text{ gallons} \times 8.34 \text{ lbs/gallon} \][/tex]

3. Perform the multiplication to find the total weight of the water:

[tex]\[ \text{Total Weight} = 5364.1212 \text{ lbs} \][/tex]

4. Round the result to two decimal places:

[tex]\[ \text{Total Weight Rounded} = 5364.12 \text{ lbs} \][/tex]

Based on these calculations, the weight added by the water to the tank is:

[tex]\[ \boxed{5364.12 \text{ lbs}} \][/tex]

So the correct answer is:

b. 5364.12 lbs.
