71. The correct prismoidal formula for volume is

72.  The area of a sloping surface of a protective embankment of mean height d, side slopes S : 1 and len h L is

73. The reduced levels of points, 30 metres apart along the longitudinal section of a road portion between chainages 5 and 9 are shown in Fig. 23.4. If there is a uniform up-gradient of the road 120 in 1, the chainage of the point with no filling or cutting is

74.  The ground surface slopes 1 in 50 along a proposed railway embankment 150 m in length. The height of the embankment at zero chainage is 0.5 m, the width is 11 m and side slopes 2: 1. If the falling gradient of the embankment is 1 in 150, the quantity of the earthwork calculated by prismoidal formula, is

75.  Pick up the correct statement from the following :

76. A portion of an embankment having a uniform up-gradient 1 in 500 is circular with radius 1000 m of the centre line. It subtends 180? at the centre. If the height of the bank is 1 m at the lower end, and side slopes 2: 1, the earth work involved.

77. A cement concrete road is 1000 m long, 8 m wide and 15 cm thick over the sub-base of 10 cm thick gravel. The box cutting in road crust is
