Mass of soil scooped

    1. The problem statement, all variables and given/known data

    Hi,

    I really need help with a problem. I have a plate and need to calculate how much soil it can dig.
    2. Relevant equations



    3. The attempt at a solution[/b
    I first calculated the volume of the scoop (a square scoop) and after that I'm stuck. Anyone have an idea?

    Volume of scoop: 0.009 m3 (I calculated this)
    density of soil: 1400 kg/m3

    How much soil can it hold?

    If the volume were 1 m3, how many kg of soil would go in ?
    If it were 0.1 m3 ? 0.2 ? 0.01 ? 0.009 ?

    How can a square scoop have a volume ?

    That's true. Well, imagine a box with no top. It has a thickness, width, length and height.
    From that, how am I going to calculate how much soil it can contain? Maybe should start with that

    hehe, np

    I still don't understand where you encounter a problem here: You have a volume and you have a weight per unit volume, so calculating the weight of this particular volume is straightforward. Right ?

    If 1 m3 weighs 1400 kg, how much does 2 m3 weigh? And 0.5 m3 ? 0.1 m3 ? 0.2 ? 0.01 ? 0.009 ?
