Question

В параллелепипеде в основании ширина 3 метра, длина в 2 раза больше.А высота на 4 м больше ширины. найти V фигуры и S основание. пж помогите у меня СОЧ не могу решить ​

Answer 1

а = 3 м - ширина

b = 3 · 2 = 6 м - длина

h = 3 + 4 = 7 м - высота

- - - - - - - - - - - - - - - - - - - - - -

S = a · b = 3 · 6 = 18 (м²) - площадь основания

V = S · h = 18 · 7 = 126 (м³) - объём параллелепипеда

Ответ: 126 м³ и 18 м².

Answer 2

Пошаговое объяснение:

3*2=6 м длина

S= ab= 6*3=18 м2

3+4=7 м высота

V=abh

V=6*3*7= 126 м3

Answer 3

Calculation of Volume and Base Area of a Parallelepiped

To find the volume (V) and base area (S) of a parallelepiped, we need to use the given dimensions. Let's break down the problem step by step.

Given information: - Width of the base = 3 meters - Length of the base = 2 times the width - Height = 4 meters more than the width

Finding the Length of the Base

The length of the base is given as 2 times the width. Since the width is 3 meters, the length would be 2 * 3 = 6 meters.

Finding the Height

The height is given as 4 meters more than the width. Since the width is 3 meters, the height would be 3 + 4 = 7 meters.

Calculating the Volume (V)

The volume of a parallelepiped is calculated by multiplying the length, width, and height. In this case, the length is 6 meters, the width is 3 meters, and the height is 7 meters. Therefore, the volume (V) can be calculated as:

V = length * width * height

Substituting the values:

V = 6 * 3 * 7 = 126 cubic meters

Therefore, the volume of the parallelepiped is 126 cubic meters.

Calculating the Base Area (S)

The base area of a parallelepiped is calculated by multiplying the length and width of the base. In this case, the length is 6 meters and the width is 3 meters. Therefore, the base area (S) can be calculated as:

S = length * width

Substituting the values:

S = 6 * 3 = 18 square meters

Therefore, the base area of the parallelepiped is 18 square meters.

To summarize: - The volume (V) of the parallelepiped is 126 cubic meters. - The base area (S) of the parallelepiped is 18 square meters.
