Aliquid-filled glass pyramid is being erected as part of a museum attraction. the pyramid is designed to be 15 feet tall with a rectangular base that is 10 feet long and 6 feet wide. what is the total amount of liquid that the pyramid can hold?
a.156 cubic feet
b.278 cubic feet
c.300 cubic feet
d.324 cubic feet

The best answer would be letter C. The volume or the amount of liquid that the pyramid can hold would be 300 cubic feet. I got this answer through solving for the volume of a pyramid with a rectangular base, which formula is '(lwh)/3'. So i multiplied everything given in the problem and divided it by 3. 

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
