Question 11 1 pts A drawing of a building is scaled at 1:40. A section of the parapet wall on the drawing is not dimensioned and measures 2.25cm from the roof slab floor level. What is the actual height (in mm) of the parapet wall represented by the drawing? Put only the number in the blank box, without any units.Question 12 1.5 pts Given the following specifications for a pad footing: 2000 x 2000 x 900 PAD N28-200 EACH WAY BOTTOM (a) Calculate the total volume of earthwork or excavated soil (in cu.m.) for six (6) pad footings. Depth of excavation includes the thickness of 150mm slab on grade and 100mm thick blinding concrete. (b) What is the total volume of concrete (in cu.m.) required for blinding concrete for six (6) pad footings? Put only the number in the blank box, without any units.
