Question

1.- A concrete pile from waterfront pier was pulled from theharbor water at Port Hueneme, California. Its dimensions were 14inches*14 inches* 15 feet (1 in = 2.54 cm). So, a) What is the surface area expressed in square feet, of asingle face of the pile? Exclude the ends of the pile. b) Determinethe total surface area, expressed in square meters, of the pile,including the ends of the pile. And c) How many cubic meters ofconcrete were used to make the pile? 1.- A concrete pile from waterfront pier was pulled from theharbor water at Port Hueneme, California.

Explanation / Answer

i assume the pile has a square cross-section. a) area of a single face = height x width = (15)(14/12) sq ft>>> compute this b) total surface area = 4(area of a face) + 2(area of an end) height = 15 ft = 15 x 12 x 2.54/100 m = 4.572 m width = 14 in = 14 x 2.54/100 = .3556 m total surface area = 4(4.572)(.3556) + 2(.3556)(.3556) sq m>>> compute this c) volume = (4.572)(.3556)(.3556) cu. m >>> computethis hope this helps!
