The question I was assigned to do, was 1.3 Surface Area #6 in the homework book.
To find the surface area of the base of this pyramid, I just looked at it like a rectangle. So I used the formula A = s² to get my answer.
I had a lot of difficulty with this question, but Mr. Backe helped me a lot to understand this question.
First, I had to find the height of one of the triangles.
BUT, it wasn't that easy. I had to use the math I learned last year, and the year before to answer this question. I had to use the "Pythegorean Theory".... I think that's what it's called. :P But yeah, I used that to find one of the sides of the triangle.
To find the surface area of this one triangle, I used this formula.
To find the surface area of the whole pyramid, I took the surface area of one triangle, multiplied it by 4, and added the surface area of the square base.
Thank you for reading my post and please leave a comment! :D
