When it Pyramid in Egypt had a height of 147 meters and contained 2.3 million stone blocks. It is estimated that rouillion tons of limestone, 8,000 tons of granite, and 500,000 tons of mortar were used in its construction. In the The diagonals of the pyramid's square base, shown below, angle of elevation at D to the top of the pyramid to be 39°. side view shown below, an ancient observer found the 5.5 intersect at C. 147 1. F. 2.3 × 106 G. 7.8 x 106 H. J. K. C side view overhead view 32. When written in scientific notation, which of the following expressions is equal to the number of blocks used to construct the pyramid? 8.3 x 105 23 x 105 78 x 105 A. 30 B. 40 C. 230 D. 320 E. 650 33. The perimeter of the pyramid's base was 920 meters when construction was completed. At that time, which of the following values is closest to the length, in meters, of each diagonal of the base? D G. 147 tan 39⁰ 147 cos 39° D Which of the following expressions is equal to the length, in meters, of DC? F. 147 sin 39⁰ 147 sin 39⁰
