Well I'm in 11th grade math which is basically algebra/a pre-introduction to calculus.

I'm doing a personal project that involves me finding out roughly how many images at 3" x 3" can fit on a car with these dimensions without covering the windows and head/brake lights:

overall length (inches): 187.6, overall width (inches): 73.9, overall height (inches): 55.7, wheelbase (inches): 107.1, front track (inches): 62.8, rear track (inches): 63 and curb to curb turning circle (feet): 33.4

It's the dimensions of an '07 mustang.

I can show you guys when I'm done, but I need to know how I would go about finding an answer.

you need to find out the surface area of the car, and divide that by the surface area of a 3" by 3" image (9 in^2).

Would just adding up those dimensions do me justice?

Not quite. Area=base*height

the problem is that a car isn't exactly a rectangular prism. you'd have to break it down into shapes for which you can find the area. things like the hood, the roof and the trunk should be simple rectangles. you can make the side profile a recangle and cut out circles for the wheel wells. be creative.

Thankfully, the current Mustang can be divided into normal shapes pretty easily. Mostly rectangle and triangle based shapes.

I took the easy way out and just went with really small images and less than I'll need. If you want to check out the project, PM me.

Thanks you guys.
