Question

Обьем деревянного бруска 4м в кубе.Определите массу бруска. ПОМОГИТЕ ПОЖАЛУЙСТА!!!!☺

Answer 1

При 12 процентов влажности доски средний вес одного кубометра составляет 600 кг. Из этого следует что вес 4 м/кубических будет составлять 2400кг. А вообще для более точного ответа требуется знать из какой породы дерева изготовлен брус и его влажность .

Answer 2

Calculating the Volume of the Wooden Beam

To calculate the volume of the wooden beam, we can use the formula: Volume = Length x Width x Height

Given that the wooden beam has a length of 4m, we can use this information to calculate the volume.

Calculating the Mass of the Wooden Beam

To determine the mass of the wooden beam, we can use the density of wood, which is approximately 0.6 to 0.8 g/cm³. Using this density, we can calculate the mass of the wooden beam.

Calculation

Using the given length of the wooden beam (4m) and the density of wood, we can calculate the volume and mass of the wooden beam.

Volume: The volume of the wooden beam can be calculated using the formula: Volume = Length x Width x Height

Given that the length is 4m, we can calculate the volume using this information.

Mass: The mass of the wooden beam can be calculated using the formula: Mass = Volume x Density

We can use the calculated volume and the density of wood to determine the mass of the wooden beam.

Results

Using the provided information, we can calculate the volume and mass of the wooden beam. Let's proceed with the calculations.

Volume Calculation: The volume of the wooden beam with a length of 4m is: Volume = 4m x Width x Height

Mass Calculation: The mass of the wooden beam can be calculated using the formula: Mass = Volume x Density

Conclusion

Based on the provided information, we can calculate the volume and mass of the wooden beam using the given length and the density of wood.
