In a site of road construction project, there is a cylindrical tank placed in horizontally position for storing fuel for the machineries of the project, where dimensions of the tank are (18.5666 ft in diameter and of length 28.05 ft). While the tank contains about 250.056 barrels of fuel, estimate the vertical depth in (m) of fuel in the tank. Q2/ Design and arrange the maximum ( aligned-loading) of a pickup truck of loading body capacity (2.90 x 2.02 x 0.98) m with bricks of size (24x12x8) cm and then find: 1- Totally number of bricks can be loaded as (maximum-best ) loading. 2- Volume of remaining space of the pickup body as a number of bricks. Q3/ Estimate needed number of dump truck of capacity 20 m for removing all quantities of soil from excavating a trapezoidal earth canal of length 450 m and of cross sectional dimensions (canal base of 3 m, depth of excavating or height of the canal 4.5 m, and of side slop as 1 horizontal to 2 vertical). Q4/ If we have two tanks for the same volume or capacity of 83 barrels made of galvanized plate-steel, one of them is cylindrical shape of diameter base (2.6 m) and the other of rectangular shape of base (1.9 x 4.1 m) in dimension. Estimate and ( (compare between ) the used quantity of plate-steel in (m) for the both tanks.
