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 )
