    What is the total area of the interior faces of this composite solid? The figure consists of 2 solid figures connected together from surface to surface. The first solid has length of eight meters, width of five meters, and height of five meters. The face that has width of five meters and height of five meters is connected to the second solid that has the exact same face. The second solid has a three-sided face. Two of the sides form ninety degrees and each measure five meters and twelve meters respectively. The twelve-meter side of the second solid and the eight-meter side of the first solid lie on the same line. Answer fifty square inches twenty-five square inches eighty square inches forty square inches

    Interior face just means it's inside the shape.

    and what would that be on a rectangular sphere and a cylinder?

    Rectangular prisms have 6 interior faces. Sphere's just have one big interior face. A cylinder has 3 interior faces.

    it's like a triangular prism and a rectangular prism and it is asking What is the total area of the interior faces of this composite solid is and I don't know what an interior face is and I am just so confused and flustered and can't figure any thing out!

    Okay, take these faces one at a time. The rectangle part is the easiest. The 4 long faces are each 8*5 The small face on the left is 5*5. There are 4 triangular faces left to deal with. Two of them, we know the base and height for. (1/2)*b*h gives (1/2)*5*12
