Comments (4) on “What is the total surface area of the square pyramid in square inches?Height is 11 in. Base is 7 in. Side Length is 11.5PLEASE”

  1. Step-by-step explanation:

    I assume that "side length" means the slant height of one of the triangular faces.

    area of a triangular face = ½(base)(side length) = ½(7)(11.5) = 40.25 in

    lateral area = all four triangles = 161 in²

    base area = 7² = 49 in²

    total surface area = lateral area + base area = 161+49 = 210 in²
