To one of twelve [million square cubits].<span class="x" onmousemove="('comment',' 8,000,000 sq. cubits and 4,000,000 sq. cubits (cf. prev. two nn.) amount to 12,000,000 sq. cubits.');">³⁰</span> Would then 'such an open space represent a quarter'? Is it not in fact more than a third of the entire area?<span class="x" onmousemove="('comment',' 12,000,000/32,000,000 being equal to 3/8.');">³¹</span>
