    the length and width of the pit remain the same, so we can consider it as a cuboid of l*b*h = 9*6*1.5 = 81

    \[Volume= length\ \times breadth\ \times depth\] Earlier Volume \[Volume=9 \times 6 \times 2=108\ feet^3 \] Now depth is increased by 1.5 feet so \[New\ Volume=9 \times 6 \times 3.5=189 feet^3\] Increase ij Volume=189-108= 81 feet^3
