| 1 cm in a cube of silver has a mass of 10.5 g. Determine the mass of a silver bar in the shape of a rectangular parallelepiped with measurements of 2.3 dm, 0.14 m and 24 cm.
1) Calculate the volume of the parallelepiped using the formula:
V = 2.3 dm * 0.14 m * 24 cm.Let us translate for convenience in cm ^ 3.
2.3 dm = 23 cm.
0.14 m = 14 cm.
24 cm – leave.
V = 23 cm * 14 cm * 24 cm = 7728 cm ^ 3.
2) Let’s make the proportion:
1 cm ^ 3 = 10.5 g.
7728 cm ^ 3 = x.
Let us express x:
x = 7728 cm ^ 3 * 10.5 g = 81144 g – the answer.
