Question

Ширина прямоугольного Параллепипеда равна 4,8 см что составляет 6/25 его длины а высота составляет 45‰ его длины вычислите объём параллепипеда

Answer 1

Длина=4,8=6/25Х Х=4,8*25/6=20см
Высота: 20см*0,45=9 см
Объем: 4,8*20*9=864см3

Answer 2

Calculation of the Volume of a Rectangular Parallelepiped

To calculate the volume of a rectangular parallelepiped, we need to know its width, length, and height.

Given: - Width = 4.8 cm, which is 6/25 of its length. - Height = 45‰ (per mille) of its length.

Let's calculate the length of the parallelepiped first.

To find the length, we can set up the following equation using the given information:

Width = (6/25) * Length

Solving for Length:

Length = Width / (6/25)

Length = 4.8 cm / (6/25)

Length = 4.8 cm * (25/6)

Length = 20 cm

Now that we have the length, we can calculate the volume of the parallelepiped.

The volume of a rectangular parallelepiped is given by the formula:

Volume = Length * Width * Height

Substituting the given values:

Volume = 20 cm * 4.8 cm * (45‰ * 20 cm)

Volume = 20 cm * 4.8 cm * (45/1000 * 20 cm)

Volume = 20 cm * 4.8 cm * (0.045 * 20 cm)

Volume = 20 cm * 4.8 cm * 0.9 cm

Volume = 86.4 cm³

Therefore, the volume of the rectangular parallelepiped is 86.4 cm³.
