If an average rectangular block of limestone used to build the Great Pyramid of Khufu at Giza is approximately 2.5 feet by 3 feet by 4 feet and limestone weighs approximately 170 pounds per cubic foot, what is the weight of one of the nearly 2,300,000 limestone blocks used to build the pyramid?

Best ResponseYou've already chosen the best response.0First find the volume of the block, then multiply by 170 volume = length *width*depth

Best ResponseYou've already chosen the best response.0can u show me that volume = length *width*depth?

Best ResponseYou've already chosen the best response.0why that is the volume? well imagine how many 1 cubic foot boxes could fit in our 2.5 by 4by3 block the base of our figure is a rectangle of length 4 and width 3 thats an area of 12 so i could draw 12 1 ft squares, now imagine each of these squares is 1 ft high, to fill up the block we would need 2.5 layers of these 12 cubes does that help at all?

Best ResponseYou've already chosen the best response.0well the volume is the total number cubes 12*2.5

Best ResponseYou've already chosen the best response.0now since each cubic foot weighs 170 lbs >30 * 170

Best ResponseYou've already chosen the best response.0correct for the other problem you posted, its done the same way except you have to find the area of the triangle first

Best ResponseYou've already chosen the best response.0Area of triangle = (1/2)*length*height

Best ResponseYou've already chosen the best response.0which is the lenght and height

Best ResponseYou've already chosen the best response.0look at the triangle part of the diagram these 2 lines represent length and height    ______________________

Best ResponseYou've already chosen the best response.0I mean the number of the triangle

Best ResponseYou've already chosen the best response.0no that was for the last problem, i thought we were talking about the triangular prism (the ramp)?
