The Volume of Complex Figures All of the formulas for volume can be found on the sheet posted at the top of the Measurement and Geometry Page This sheet will be provided to you on all quizzes, tests, and exams, so there is no need to memorize the structure. We will try an example of each of the more complex formulas just to be sure we are clear on the order of operations the Great Pyramid of Khufu • The Great Pyramid of Giza. Built in 2560 BC, it is the oldest and largest of the three pyramids in the Giza Necropolis. This pyramid is 147m tall. The length of each base side is 230 m Determine its volume Find the Volume of the Pyramid V = (L)(W)(H) 3 V = (230m)(230m)(147m) 3 147 V = 7 776 300 m3 3 V = 2 592 100 m3 230 230 A snow cone has a radius of 5 cm and a height of 20 cm Find the volume of sugar ice that it can hold. r2h 3 V = 5220 3 V= 20 5 V =1570 3 V =523.3 cm3 radius = 695 500 km The radius of a basket ball is 12 cm.
