correct question=> 2.8m³
instead of 2.8m. and bags of grais
needed instead of bags needed
Step-by-step explanation:
Volume of drum= πr²h= 3.14×4.2×4.2×5
= 276.948 m³
number of bags= vol of drum/ vol of 1 bag
= 276.948/2.8= 98.91
this means 99 bags are needed to fullfil.
answer= 99 bags

note -- how many bags are needed is written in this question and not mentioned these bags are grain bags or not . this is possible to other bags then we can not decide the number of bags to fullfil.
