Spring Break: Day One

Students in 1, 3, and 4°, remember that you have a posttest on April 3rd once we return.  Below is a question and video that you can use to help review/prepare for the posttest.  If you would like, you are encouraged to post an answer to the question below.

The largest pyramid in the world was built around 2500 B.C. by Khufu, or Cheops, a king of ancient Egypt.  The pyramid had a square base, 756 feet on each side, and a height of 482 feet.  Find the volume of Cheops’ pyramid.




Students in 2°, you are almost halfway through Chapter Eight.  Up to this point, we have discussed customary unit measures, significant digits, and circumference of a circle.  Once class resumes, it is expected that you can recall this information for a Quick Check.   If you would like, you are encouraged to post an answer to the question below.

Molly is putting an 8-foot diameter circular flower garden in her yard.  She will put plastic
edging along the flowerbed. How many feet of edging will Molly need to enclose her flower garden?



This is my friends and I base jumping
from Mt. Everest.  We do small
things over Spring Break.

      I get the same answer Gibel. Nice job of justifying your work. You are another step closer to being prepared for the Chapter Nine Posttest.

    My final answer for the first problem was 91,826,784 cubic feet. Here is how I got it. Since the pyramid formula to find the volume of a pyramid is: V= B x h / 3, you have to find the area of the square base and the formula to find the area of a square is: l x h. So since it is a square the number you plug in are 756 x 756 and that equals 571,536. Then you have to multiply the area of the base by the height and since the height is 482 feet, you multiply that by the area of the square base which equals 275,480,352 feet, but this is not your final answer you still have to divide by 3 and once you dived by 3 you end up with 91,826,784 cubic feet and that is your final answer.

    I like how detailed you are in your explanation Steroig! If you can handle this problem, you are on your way to a successful Chapter Nine Posttest.

    It would be 8pi.

    Nice answer and I like that it is terms of pi.

    I got 91,826,784 by using the formula l x w x h / 3=volume of pyramid square base. Since it is a square base the length and the width are the same thing so you multiply 756 x 756=571,536. I also knew the height was 482 so I multiplied 571,536 x 482=275,480,352. Finally I divided the last answer I got by 3 and that equals 91,826,784 cubic feet

    I got the answer: 91,826,784 by multiplying 756 by itself then multiplying that answer (571,536) by 482 and dividing that by 3 which gives me the answer. :)
