    V_{prism}=l\cdot{w}\cdot{h}

    A_{base}l\cdot{w}=20 make as substitution

    V_{prism}=40=20\cdot{h}\Rightarrow{h=2}

    The volume of a rectangular prism is v=lwh

    We are given the area of the base which takes care of the length and width so now we have,

    40cm^3=20cm^2*h

    So to isolate the height we divide both sides by 20cm^2 which gives us,

    \frac{40cm^3}{20cm^2}=h=2cm
