    2. Relevant equations
    M=Fd

    3. The attempt at a solution
    not sure how to get the height here. thanks
    im assuming the distance they are asking is less than 72 in. but im not sure how to find that.
    I guess i would need to put my forces in a formula where d is not the variable.
