Question

Знайдіть довжину прямокутного паралелепіпеда обєм якого дорівнює 13,5 см, ширина-4,5мм,а висота 4мм

Answer 1

объем находится по формуле: ширина*длина*высота

13,5 см = 135 мм

подставим в формулу все известное, длину возьмем за х.

4,5*4*х=135

18х=135

х=7,5

ответ: длина равна 7,5 мм.

Answer 2

Ответ:

0,75 см

Пошаговое объяснение:

Объем ,очевидно, 13,5 см. куб.

Длина  13,5/(4,5*4)=27/(9*4)=3/4=0,75 см

Answer 3

Calculation of the Length of a Rectangular Parallelepiped

To find the length of a rectangular parallelepiped, we need to use the formula for the volume of a rectangular parallelepiped and rearrange it to solve for the length.

The formula for the volume of a rectangular parallelepiped is:

Volume = Length × Width × Height

Given that the volume of the rectangular parallelepiped is 13.5 cm³, the width is 4.5 mm, and the height is 4 mm, we can substitute these values into the formula and solve for the length.

Let's convert the width and height to centimeters for consistency:

Width = 4.5 mm = 0.45 cm Height = 4 mm = 0.4 cm

Now we can substitute the values into the formula:

13.5 cm³ = Length × 0.45 cm × 0.4 cm

To solve for the length, we divide both sides of the equation by (0.45 cm × 0.4 cm):

Length = 13.5 cm³ / (0.45 cm × 0.4 cm)

Calculating this expression gives us the length of the rectangular parallelepiped.

Let's perform the calculation:

Length = 13.5 cm³ / (0.45 cm × 0.4 cm) = 60 cm

Therefore, the length of the rectangular parallelepiped is 60 cm.
