Pyramids of Egypt

 View Puzzle Solve Puzzle
Fill in the blanks

 My Dad has a miniature Pyramid of Egypt. It is 5 inches in height. Dad was invited to display it at an exhibition. Dad felt it was too small and decided to build a scaled-up model of the Pyramid out of material whose density is (1 / 8) times the density of the material used for the miniature. He did a "back-of-the-envelope" calculation to check whether the model would be big enough.If the mass (or weight) of the miniature and the scaled-up model are to be the same, how many inches in height will be the scaled-up Pyramid? Give your answer to two places of decimal. .fixedToBottom { position:fixed; _position:absolute; right:0; bottom:2; _top:expression(document.body.scrollTop+document.body.clientHeight-this.clientHeight - 256); } Hint
