Question

Длина прямоугольника параллелепипеда равна 50см,ширина составляет 80% длины,а высота -2/5 длины.найти объем этого параллелепипеда.

Answer 1

50*80:100=4см-ширина
50*2:5=20см-высота
4*20*50=4000смВкубе

Answer 2

Problem Analysis

We are given the length, width, and height of a rectangular parallelepiped and we need to find its volume. The length is given as 50 cm, the width is 80% of the length, and the height is -2/5 of the length.

Calculation

Let's calculate the width and height of the parallelepiped using the given information:

Width = 80% of Length = 0.8 * 50 cm = 40 cm.

Height = -2/5 of Length = (-2/5) * 50 cm = -20 cm.

Now, we can calculate the volume of the parallelepiped using the formula:

Volume = Length * Width * Height.

Substituting the values, we get:

Volume = 50 cm * 40 cm * (-20 cm).

Answer

The volume of the parallelepiped is -40,000 cubic centimeters.
