To calculate how many gallons of paint Lisa will need to paint one side of her fence, we need to know the total area (in square feet) of that side.

The formula for the required number of gallons of paint is:

$\text{Gallons of paint needed} = \frac{\text{Total surface area}}{\text{Coverage per gallon of paint}}$

Given:

• Coverage per gallon of paint = 350 square feet

If you provide the total area of one side of Lisa's fence, I can complete the calculation for you. Could you provide those dimensions (height and length of the fence)?

Let me know if you need further assistance or clarification. Here's a list of relative questions:

1. What are the dimensions of one side of Lisa's fence?
2. Does Lisa intend to paint multiple sides of the fence?
3. Is the fence height consistent along its entire length?
4. Does the type of paint (e.g., thickness) impact coverage in any way?
5. Is there any gate or door on the fence that would reduce the painting area?

Tip: Always measure surface area carefully before buying materials to avoid under- or over-purchasing.
