Matlab question

  1. Jan 22, 2013 #1
    1. The problem statement, all variables and given/known data
    I have a couple of matlab questions hopefully you guys can help me out

    40).The volume of a right prism is base area * vertical_dimension. Find the volumes of the prisms with triangles of problem 29 as their bases, for vertical dimensions of 10.

    I don't understand which part of 29 they want me to incorporate. Question 29 reads the area of a triangle s 1/2 base* height define the base of the matrix as b=[2,3,6]

    Would I use the area of question 29 as the base area in question 40?


    Create a B matrix by extracting the first column of matrix A

    I'm trying B= A(1,:)

    Thanks for the help guys.

    And it doesnt seem to be working..




    2. Relevant equations



    3. The attempt at a solution

    That would be my reading. #29 has a bunch of triangles which are to be used as basis for right-prisms. Probably you should implement the method from #29 for finding the area or a triangle.

    In what way?
    What does it do instead of what you want?
    (Once you have described the problem, the solution should leap out at you.)
