    Re: Maths Assignment

    Volume V of prism = triangle's area A times depth of prism D; V = AD, so D = V/A

    Triangle's area (right triangle, since 3rd side = 7) = 4.5(5.36)/2 = make it 12

    Since volume = 164, then depth D = 164 / 12 = 13.6

    Next time you post a problem, post the original problem, not your version...OK?
