World Trade Center – Square Prisms New York City
The north tower was opened in Dec. 1970 and the south tower in Jan. 1972. • Used for office buildings but also contained restaurantsand observatories • 208 ft by 208 ft at base • 1,368 ft high (north tower) • 1,362 ft high (south tower) • http://www.infoplease.com/spot/wtc1.html
North Tower • S.A. = 2B + Ph = 2(208²) + (208 X 4)(1368) = 2(43,264) + (832)(1368) = 86,528 + 1,138,176 = 1,224,704 ft² • Volume = Bh = (208²)(1368) = (43,264)(1368) = 59,185,152 ft³
Rainforest Pyramid – Square Pyramid Moody Gardens in Galveston, Texas
Opened in 1993 • Use: Home to more than 1,700 exotic plant and animal species from the Asian rainforests, tropical Americas, and Africa. Also contains a Visitor Center, Restaurant, light/fountain show, and America's first IMAX s® 3D Theater • Dimensions: 70yd X 70yd square base and 33yd height and approx. 48yd slant height • www.portledge.org/homework/jsillat/documents/10.6lecture.ppt(slide 14)
S.A. = B + ½ P l = (70²) + ½ (70 X4)(48) = 4900 + ½ (280)(48) = 4900 + 6720 = 11,620 yd² • Volume = ⅓ B h = ⅓ (70²)(33) = ⅓ (4900)(33) = 53,900 yd³

S.A. = 4πr² = 4(3.14)(20²) = 4(3.14)(400) = 5024 ft² V = 4/3(π)(r³) = 4/3(3.14)(20³) = 4/3(3.14)(8000) ≈ 33,491 ft³
