    Surface Area to Volume ratio calculation
    Hey everyone:

    This isn´ t homework help I´m just getting prepared for the next semester. I was researching this online and in books and the nearest GOOD library is 20 miles away so I decided a helpdesk would be the best option.

    To the point. I have already learned how to calculate the surface area to volume ratio of simple shapes, such as cubes or spheres but here is something I do not understand at all.
    If the diametre of "x" is 5 inches and the height of "x" is 2 inches and the volume of x is 3 cubic inches then what is the surface are to volume ratio?

    Please post a formula or something, or even better show me how to calculate the thing in steps. Please, this isn´t homework help, I´m just getting ready for the stuff we are going to learn in a month.

    Thanks,
    OhioKyle

    Well I guess diametre would be width?

    Sounds like they gave you width and height, but not length.

    10x = 3, so divide by 10 on both sides to get x. Then you can find your surface area, and get your ratio.

    Is this what you are looking for?

    What geometrical figure is it? Doesn't that make a difference too?

    Cube side3
    Rectangular Prism side1 * side2 * side3
    Sphere (4/3) * pi * radius3
    Ellipsoid (4/3) * pi * radius1 * radius2 * radius3
    Cylinder pi * radius2 * height
    Cone (1/3) * pi * radius2 * height
    Pyramid (1/3) * (base area) * height
    Torus (1/4) * pi2 * (r1 + r2) * (r1 - r2)2
