Q: What is the thickness of one and half brick wall made up of standard modular brick?
  • A. 20
  • B. 30
  • C. 40
  • D. 50
Correct Answer: Option B - Since the size standard modular brick is 19cm  9cm  9cm so when the one and the half brick wall is constructed the thickness of wall becomes 19cm + 1cm (mortar) + 9cm = 29cm So more accurate option is (b) i.e. 30cm.
