b) Volume of the tank = It's capacity.

c) soil required = volume of brick.

d) lateral surface are of a cube is required since the dice is a cube.

here is the representation of the optional trigonometric situation-

Let AB be the tower, CD be the building, BD be the distance between the two.

Also, E is the the point perpendicular to CD from the Point of View (C).

Therefore, DB is parallel to CE and DB=CE=7m.

angle ACE = 60 deg.

angle ECB = 45 deg.
