 Question 193071: Hi, my class just started studying pyramids and I need help on a problem. I'm really terrible at geometry and we don't take notes in our class and would really appreciate some help! This is how the problem is worded exactly in my book: "The TransAmerica building in San Francisco is built of concrete and is shaped like a square-based pyramid. The building is periodically power-washed using one gallon of cleaning solution for every 250 square meters of surface, As the new building manager, you need to order the cleaning supplies for this large task. The problem is that you do not know the height of each triangular face of the building; you only know the vertical height of the building from the base to the top vertex." "Your Task: Determine the amount of cleaning solution needed to wash the TransAmerica building if an edge of the square base is 96 meters and the height of the building is 220 meters. Include a sketch in your solution." I have the answers from another website, but it doesn't show how to get them. I've tried to get the solutions, but have no idea what process I must got through. The answers are as follows: Surface Area≈43,234 square meters. This does not include the area of the base, which is 9, 216 square meters. Therefore, ≈173 gallons of cleaning solution are needed.

 Question 193341: The area of a rectangle is twice the area of a square. If the length of a rectangle is 10 inches, and if the width of the rectangle is the same as the length of a side of the square, find the dimensions of both the rectangle and the square. (Hint, draw a picture of both the rectangle and the square.) This is not from a book, it is a question from a math review that I can not figure out how to answer and the book we have does not help at all. Thank you very much.
