Question

Помогите пожалуйста очень срочно : Определите объем аквариума, если его длина 1м, ширина в 2 раза меньше длины и на 30см, меньше высоты. Ответ дайте в дм³

Answer 1

Ответ:

1 м = 100 см

1) 100 - 30 = 70 см - ширина аквариума

2) 70* 2 = 140 см - высота аквариума

V = a*b*c - объем, где a,b,c - длина, ширина, высота

V = 100 * 140 * 70 =980000 см³

1 дм³ = 1000 см³

980000см³ = 980 дм³

Ответ: 980 дм³.

Calculation of Aquarium Volume

To determine the volume of the aquarium, we need to calculate the length, width, and height of the aquarium based on the given information.

Given: - Length = 1m - Width = 2 times smaller than the length - Height = 30cm less than the width

Let's calculate the width and height of the aquarium first:

1. Width: - The width is 2 times smaller than the length, so the width = 1m / 2 = 0.5m.

2. Height: - The height is 30cm less than the width, so the height = 0.5m - 0.3m = 0.2m.

Now that we have the length, width, and height of the aquarium, we can calculate the volume.

The formula to calculate the volume of a rectangular prism (like an aquarium) is:

Volume = Length x Width x Height

Substituting the values we calculated:

Volume = 1m x 0.5m x 0.2m

Converting the units to dm³ (cubic decimeters):

1m = 10dm 0.5m = 5dm 0.2m = 2dm

Volume = 10dm x 5dm x 2dm = 100dm³

Therefore, the volume of the aquarium is 100 dm³.
