Question

PLS HELP!!!
A triangular prism. The rectangular sides are 12 feet by 3 feet, 12 feet by 5 feet, and 12 feet by 4 feet. The 2 triangular sides have a base of 3 feet and height of 4 feet. The area of each triangular base is: A = 1/2(b)(h) A = 1/2(3)(4) A = ft2 There are two bases, so total base area is ft2. The lateral area is: A = (12)(3) + 12(5) + 12(4) A = ft2 The total surface area is ft2.

    Answer:

    6, 12, 144, 156

     

    Step-by-step explanation:

    The area of each triangular base is:  A = 1/2(b)(h)  A = 1/2(3)(4)  A =  6  ft2

    There are two bases, so total base area is  12  ft2.

    The lateral area is:  A = (12)(3)  + 12(5) + 12(4)  A =  144  ft2

    The total surface area is 156  ft2.
