Ответ:
m= 4,599.145 g
Explanation:
Let m = mass, d = density and V = volume of the osmium block.
m = d x V
m = 22.610 g/cm3 x (6.70 x 9.20 x 3.3) cm3
m = 4,599.145 g

medium rectangles = 2 x 2 x 6
small rectangles = 2 x 2 x 3
surface area = large rectangles + medium rectangles + small rectangles = 36 + 24 + 12 = 72 cm^2
