Question

1. З якого матеріалу виготовлений дитячий кубик, об'єм якого дорівнює 250 см3, а маса 110 г? ​

Answer 1

Ответ:

Объяснение:

V = 250 cм³

m = 110 г

Материал - ?

===========

Плотность кубика:

ρ = m / V = 110 / 250 = 0,44 г/см³ или 440 кг/м³

Вероятно, кубик изготовлен из сосны.

Answer 2

Material and Volume of the Cube

The material of the cube can be determined using the formula for density, which is mass divided by volume. In this case, the volume of the cube is 250 cm³ and the mass is 110 g. By rearranging the formula, we can solve for the material.

The formula for density is: Density = Mass / Volume

By rearranging the formula, we get: Mass = Density × Volume

So, the material of the cube can be determined by calculating the density using the given mass and volume.

Calculation

Let's calculate the density of the cube using the given mass and volume: Density = Mass / Volume Density = 110 g / 250 cm³

Material of the Cube

The material of the cube can be determined by comparing the calculated density with the known densities of common materials.

Based on the calculated density, the material of the cube is likely to be plastic. This is a common material used for manufacturing various items, including children's toys.
