Question

Визначте об'єм залізного тіла, якщо його маса 780 грам.

Answer 1

$m = 780$ г = 0,78 кг
ρ = 7800 кг/м³
V - ?

m = ρV
V = m/ρ
V = 0,78/7800 = 0,0001 м³

Answer 2

Calculating the Volume of an Iron Object

To calculate the volume of an iron object, we can use the formula:

Volume (V) = Mass (m) / Density (ρ)

Given: - Mass (m) = 780 grams - Density of iron (ρ) = 7.87 g/cm³

Using the formula, we can calculate the volume as follows:

V = m / ρ

V = 780 g / 7.87 g/cm³

V ≈ 99.11 cm³

So, the volume of the iron object is approximately 99.11 cubic centimeters.
