Incidentally, it is incorrect to calculate the full length of the hallway to be 120 meters by multiplying 33 and 2 and 1.82 together, based on the premises that each of the 33 column spacings is equivalent to "2間" (2 ken) and that 1間 is about 1.82m.
なお、「33ある柱間は長さ2間に相当するから堂の全長は33×2×1.82で約120ｍ」とするのは誤り。
