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?

First find the volume of the block, then multiply by 170 volume = length *width*depth
anonymous
  • anonymous
can u show me that volume = length *width*depth?

dumbcow
  • dumbcow
why 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?

  • anonymous
then what happen next
dumbcow
  • dumbcow
well the volume is the total number cubes 12*2.5
anonymous
  • anonymous
i got 30
dumbcow
  • dumbcow
correct
dumbcow
  • dumbcow
now since each cubic foot weighs 170 lbs ->30 * 170
anonymous
  • anonymous
is that a neg?
dumbcow
  • dumbcow
no sorry its an arrow
anonymous

my bad

dumbcow
  • dumbcow
correct for the other problem you posted, its done the same way except you have to find the area of the triangle first
anonymous
  • anonymous
which is
dumbcow
  • dumbcow
Area of triangle = (1/2)*length*height
anonymous
  • anonymous
which is the lenght and height
dumbcow
  • dumbcow
look at the triangle part of the diagram these 2 lines represent length and height | | | ______________________
anonymous
  • anonymous
I mean the number of the triangle
dumbcow
  • dumbcow
its on the diagram
anonymous
  • anonymous
1/2 (3)x2.5?
dumbcow
  • dumbcow
no that was for the last problem, i thought we were talking about the triangular prism (the ramp)?

oop my bad
