no. I posted my question here because that one is complicated and I don't understand it
ok, i will try to rephrase it
and could you keep in mind it is sixth grade math?
actually @SmoothMath Would you like to handle this one?
you are better at explaining than me
would you like me to post the homework question to make it easier?
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?
No such thing as a rectangular sphere...
rectangle, sphere, and cylinder
A rectangular prism, probably.
Rectangular prisms have 6 interior faces. Sphere's just have one big interior face. A cylinder has 3 interior faces.
I meant this ->|dw:1336260886636:dw|
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!

oops... I am on the wrong assignment... that would be why... lol!
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
