Answer:
10.05 tonnes
Step-by-step explanation:
Total volume = volume of cylinder + volume of cuboid
= πr²h + (80 × 80 × 140)
= [tex]\frac{22}{7} \times 40^{2} \times 70 + 896000[/tex]
= 352000 + 896000
= 1248000 cm³
Now, density of steel 8.05 gm/ cm³
Therefore, the total mass of the sculpture is (1248000 × 8.05) = 10046400 gm = 10.05 tonnes. ( Answer )
