70% to pass

Ten triangular piles of piping on the pier are to be loaded - each pile has a 20 foot base, is 15 feet high and 30 feet long. If the breadth of the hold is 60 feet and the piping is to be stowed fore and aft in a 30 foot space, how high will it stow?

A 16.6 feet
B 25.0 feet
C 50.0 feet
D 75.0 feet
AI Explanation

The correct answer is B) 25.0 feet. To explain the reasoning: 1) Each triangular pile of piping has a base of 20 feet, a height of 15 feet, and a length of 30 feet. 2) With 10 piles to be stowed in a 30 foot space, the total volume of the piping is 10 * (1/2 * 20 * 15) = 1500 cubic feet. 3) Given the 60 foot breadth of the hold, the piping can be stowed in a space 30 feet long and 50 feet high to accommodate the 1500 cubic feet. 4) Therefore, the correct answer is that the piping will stow 25.0 feet high. The other options are incorrect because: A) 16.6 feet is too low to accommodate the full volume of the piping. C) 50.0 feet is taller than necessary to stow the piping. D) 75.0 feet is excessively tall and would not be the correct height.
