Answer:
THE TOTAL SURFACE AREA OF THE MATERIAL =
CSA OF CUBE + AREA OF BASE + CSA OF CYLINDER +
{AREA OF TOP - AREA OF CIRCLE}
= 4a²+ a²+ πr²h + {a²-πr²}
= 5a²+2πrh + {a²-πr²}
= 5 (5)²+ 22/7 × 2× 2 × 20 + {5²-22/7 × 2 × 2}
= 125 + 1760/7 + 175-88/7
= 125 + 1760/7 + 87/7
= 875+87+1760/7
= 2722/7
= 388.85 m
