Answer:
10.04563 t
Step-by-step explanation:
mass = density multiplied by volume
volume of cuboid = width x length x height = 80x80x140=896,000 cm³
mass of cuboid = 8.05 x 896,000=7,212,800 g
volume of cylinder = πr²x height= 3.142x40²x70=3.142x112,000=351,904 cm³
mass of cylinder = 8.05 x 351,904=2,832,827.2 g
mass of sculpture =mass of cylinder + mass of cuboid = 2,832,827.2 + 7,212,800 = 10,045,627.2 g = 10.04563 t
