Question

СРОЧНО!! ДАЮ 20 БАЛЛОВ! (p.s. плиз пишите как вы решили задание) Задание: Рассчитайте 25 % объема с размерами 3 дм; 0,5 м и 45 см!

Answer 1

Ответ:

25% это 1/4

3 на 4 мы не поделим. Поэтому будем брать см.

30÷4×1=7,5 см

0,5 м это 5 дм и это 50 см

50÷4×1=12,5 см

45 ÷4×1=11,25 см

Answer 2

Calculation of 25% of a Volume

To calculate 25% of a volume with dimensions of 3 dm, 0.5 m, and 45 cm, we need to find the volume first and then calculate 25% of that value.

The formula for calculating the volume of a rectangular prism is:

Volume = Length x Width x Height

Given the dimensions: Length = 3 dm Width = 0.5 m Height = 45 cm

We need to convert the dimensions to a consistent unit before calculating the volume. Let's convert all the dimensions to meters.

1 dm = 0.1 m (since 1 decimeter is equal to 0.1 meter) 1 cm = 0.01 m (since 1 centimeter is equal to 0.01 meter)

Converting the dimensions: Length = 3 dm = 3 x 0.1 m = 0.3 m Width = 0.5 m Height = 45 cm = 45 x 0.01 m = 0.45 m

Now we can calculate the volume: Volume = Length x Width x Height = 0.3 m x 0.5 m x 0.45 m = 0.0675 cubic meters

To find 25% of the volume, we multiply the volume by 0.25: 25% of the volume = 0.0675 cubic meters x 0.25 = 0.016875 cubic meters

Therefore, 25% of a volume with dimensions of 3 dm, 0.5 m, and 45 cm is approximately 0.016875 cubic meters.

I hope this helps! Let me know if you have any further questions.
