    \[Vrec = (length)\times(width)\times(height)\]\[Vsquaqre pyram = {((lenght)^{2} \times height) \over 3} \] Vtotal = Vrec + Vsquarepyram

    ops, typo, not a square base, rectangular base: instead of (lenght)^2 should be (length)*(width)

    ½ * a * b * h = Ah (area of the triangle)*(lenght of the prim / height of the prim)

    no problem, its the same idea however the formulas are different

    how do I find the area of the triangle if I don't have the height?

    to find the volume of the triangular prism, you need the area of the triangle. In order to find the area of the triangle we need the height. We can find it by: |\ x | \ 24 | \ |___\ (22/2) = 11 so 24^2 = x^2 + 11^2 x=21.3307

    now that we found the height of the triangle we can find the volume of the triangular prims and add to the volume of the rect. prism. to get the total volume

    oh okay I just forgot that we had the base. So i did 21.3307*22 all over 2 and I got 234.6377. then I did (234.6377)*(40)*(18)=169,939....is that wrong?

    alright so, Volume of Trian. prism = (.5)(22)(21.3307)(40) = 9385.51 Volume of Rect. prism = 22*18*40 = 15840 Total Volume = 9385.51 + 15840 = 25225.5
