Question

Can u please answer the question

Answer 1

≈ 10045259.94 g

Explanation:

density=mass/volume , mass=density×vol. , vol= 80²×140 + 70×40²π ≈ 1247858.377cm³

mass=vol×dens.≈ 10045259.94 g

Answer 2

10.04563 t

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
