Question

Определи массу мраморного бруска размерами 50см*30см*20см​

Answer 1

Ответ:

Объяснение:

a = 50 см = 0,5 м

b = 30 см = 0,3 м

h = 20 см​ = 0,2 м

ρ = 2700 кг/м³

m - ?

============

V = abh = 0,5·0,3·0,2 = 0,03 м³

m = ρV = 2700·0,03 = 81 кг

Answer 2

Calculating the Mass of the Marble Block

To calculate the mass of the marble block, we can use the formula:

Mass = Density × Volume

The density of marble is approximately 2.5 g/cm³.

The volume of the marble block is given as 50 cm × 30 cm × 20 cm.

Calculation

Using the given values, we can calculate the mass of the marble block:

Volume = 50 cm × 30 cm × 20 cm = 30000 cm³

Mass = 2.5 g/cm³ × 30000 cm³ = 75000 g

Therefore, the mass of the marble block with dimensions 50 cm × 30 cm × 20 cm is 75000 grams.
