Question

ПОМОГИТЕ.. длина прямо угольного параллелепипеда равна 45, а ширина состовляет 4/9 длины и 12/7 высоты . найти объем.

Answer 1

1) 45*4/9 = 20 - ширина,
2) 20 : 12/7 = 20 *7/12 = 11 2/3 - высота,
3) 45 * 20 * 11 2/3 = 900 * 35/3 = 10500 - объем

Answer 2

Calculation of the Volume of a Rectangular Prism

To find the volume of a rectangular prism, we need to multiply its length, width, and height.

Given: - Length = 45 - Width = (4/9) * Length - Height = (12/7) * Length

Let's calculate the volume.

Step 1: Calculate the width of the rectangular prism. The width is given as (4/9) times the length. Width = (4/9) * 45

Step 2: Calculate the height of the rectangular prism. The height is given as (12/7) times the length. Height = (12/7) * 45

Step 3: Calculate the volume of the rectangular prism. Volume = Length * Width * Height

Now, let's substitute the values and calculate the volume.

Step 1: Calculate the width: Width = (4/9) * 45 = 20

Step 2: Calculate the height: Height = (12/7) * 45 = 77.14285714285714 (rounded to 14 decimal places)

Step 3: Calculate the volume: Volume = 45 * 20 * 77.14285714285714 = 69300 cubic units

Therefore, the volume of the rectangular prism is 69300 cubic units.
