Question

You have a [x]-gallong water tank that weights [y] pounds when empty. With some water added to the tank, it now weighs [z] pounds. How many gallons of water are in the tank? Round to the nearest whole number.

Answer 1

To calculate the number of gallons of water in the tank, subtract the weight of the empty tank from the total weight with water, and then divide by the weight per gallon of water, which is approximately 8.34 pounds.

Step-by-step explanation:

To find out how many gallons of water are in the tank, we need to subtract the weight of the empty tank from the total weight of the tank with the water. We'll use the information given that 1 gallon of water weighs approximately 8.34 pounds (as this is a common approximation for the weight of a gallon of water).

The formula to find out the volume of water in gallons is:

• Volume of water (in gallons) = (Weight with water - Empty weight) / Weight per gallon of water
• Volume of water (in gallons) = (z - y) / 8.34

Once we have this value, we would round it to the nearest whole number to get the final answer.
