Answer 1

Answer:

672 cubic meters

Step-by-step explanation:

volume of Mortar = 2/7 (volume of whole structure)

= 2/7 ( volume of cone + volume of cylinder + volume of cubical plinth )

= 2/7 ( pi × r^2×h + 1/3 × pi × r^2× h) +2/7 × volume of cube

= 616 + 56

= 672 cubic meters

Note : height of cone = height of cylinder= 21/2 m

Radius = 14/2 = 7 m
