In ancient Egypt, small distances were measured in Egyptian cubits. An Egyptian cubit was equal to 7 palms, and 1 palm was equal to 4 fingers. If 1 finger was equal to 18.75 mm, convert 6 Egyptian cubits to meters.

(a) A pyramid has a height of 462 ft and its base covers an area of 12.0 acres (see figure below). The volume of a pyramid is given by the expression covers V = Bh, 3 where B is the area of the base and h is the height. Find the volume of this pyramid in cubic meters. (1 acre = ! 1 A FI 2.27e6 Enter a number. (b) What If? If the height of the pyramid were increased to 520 ft and the height to base area ratio of the pyramid were kept constant, by what percentage would the volume of the pyramid increase? % m³ N 2 Q F2 W S X # www 3 20 F3 E D $ 4 C @ 000 DOD F4 R F % 5 V F5 T G MacBook Air 6 F6 Y B & SN 7 H 8 F7 U :43,560 ft²) N +00 * 8 J DII FB 1 ( 9 M K FO O O < ge A F10 P : I + { OUR TEACHER [ F12 11 delete
