CHAPTER VIII-CALCULATIONS REGARDING EXCAVATIONS. '269 hastas. That (platform) is built up of bricks. O you who know calculation, say how many bricks there are (in it). 46. A raised platform, equilaterally trangular (in section), having 8 hastus (as its side measure), and 9 hastas as height, has been constructed with the aforesaid bricks. Calculate and say how many bricks there are in this (structure). 47. A raised platform, circular in section, having a diameter of 8 hastas and a height of 9 lustas is built np with (the same aforesaid) bricks. O you who know calculation, say how many bricks there are in it. 48. In the case of (a raised platform having) an oblong (section), the length is 60 hastas, the breadth 25 hastas, and the height is 6 hastas. Give out in this case the measure of that brick pile. 49. A Boundary wall is 7 hastas in thickness, 24 hastas in length and 20 hastas in height. How many are the bricks used in building it? 50. The thickness of a boundary wall is 6 hastas at the top and 8 hastas at the bottom; its length is 24 hustas and height 20 hastas. How many are the bricks used in building it? 51. (In the case of a raised sloping platform), the heights are (respectively) 12, 16 and 20 hastas (at three different points); 20 50-51. In finding out the cubical contents of the wall, the average breadth calculated accor ding to the rule, given in the lat- ter half of stanza 4 above, is used; so the Kaman- tika value is taken into con- sideration here. 513. This sloping platform is bounded at its two ends by two vertical planes, the top and the side surfaces alone 2 24 3 4 12 being sloping. The top forms an inclined.
