The solid is made up of the cuboid part and the pyramid part
The volume of the cuboid is, l×w×h
14 ×14×11 =2156 cm³
The volume of the pyramid; 1/3 base area × vertical height
that is; 1/3 ×14 ×14 ×12=784 cm³
Therefore, the the total volume = 2156 +784 =2940 cm³
but 1 cubic centimeters has a weight of 1.9 g
Thus the amount of sand will be
 2940 ×1.9=  5586 g or 5.586 kg
