    This is calculus you moron.

    We aren't going to teach you calculus. Wait for 4 more years then you'll learn it you nerd.

    Forget these noobs Redwan.. i did it without calculus which is probz the way ur teacher expects u to do it at this stage....

    u know volume of prism = area of base * height
    here the height is is the deapth which is the z axes ie, 4
    draw it out & it'll help Smile

    here is my working.. its a rough copy. Hope it helps!
    u'll have to click on "enlarge this image" to see it properly, lol

    Maybe it is possible without Cal. But what I do know is that this cannot be 8th grade question.
