Question

Полый алюминиевый куб с ребром 10см имеет массу 1кг. Какова толщина стенок куба?

Answer 1

A= 0.01 м
m= плотность× обем ( плотность алюминия возьми из инета)
знаходич от сюда обем и делиш его на 0.01м

Answer 2

Calculating the Thickness of the Aluminum Cube's Walls

To calculate the thickness of the walls of the aluminum cube, we can use the formula for the volume of a cube and the given mass of the cube.

The formula for the volume of a cube is given by: V = s^3 Where: - V is the volume of the cube - s is the length of one side of the cube

The mass of the cube is given as 1 kg.

Using the formula for the volume of a cube, we can calculate the length of one side of the cube: s = (V)^(1/3)

The density of aluminum is approximately 2700 kg/m^3.

The mass of the cube can be converted to volume using the density of aluminum: V = m / ρ Where: - V is the volume - m is the mass - ρ is the density

Let's calculate the thickness of the walls of the aluminum cube using the provided information and the formulas.

Calculation

Given: - Mass of the aluminum cube, m = 1 kg - Density of aluminum, ρ = 2700 kg/m^3 - Acceleration due to gravity, g = 9.8 m/s^2 - Length of one side of the cube, s = 10 cm = 0.1 m

Using the formula for the volume of a cube: V = s^3

The volume of the cube is: V = 0.1^3 = 0.001 m^3

Using the formula for the volume of the cube and the density of aluminum: V = m / ρ

The length of one side of the cube can be calculated as: s = (V)^(1/3) = (0.001)^(1/3) = 0.1 m

The thickness of the walls of the aluminum cube can be calculated using the length of one side of the cube: Thickness = (s/2)

Conclusion

The thickness of the walls of the aluminum cube with a side length of 10 cm is 5 cm.

This calculation is based on the given mass of the cube, the density of aluminum, and the formula for the volume of a cube.
