Question

Детский надувной бассейн имеет высоту 30см, а его дно представляет собой квадрат со стороной 1м. Сколько весит такой бассейн с водой?

Answer 1

РЕШЕНИЕ
Для воды - плотность -  ro = 1т/м³ = 1000 кг/м³ = 1 кг/дм³
Объем бассейна по формуле
S = 1 м² - площадь основания.
V = S*h = 1 * 0.3 = 0.3 м³ - объем
M = ro*V = 1 т/м³  * 0,3 м³ =   0,3 т = 300 кг - масса бассейна - ОТВЕТ

Answer 2

Calculating the Weight of the Inflatable Pool with Water

To calculate the weight of the inflatable pool with water, we can use the formula:

Weight = Volume × Density

First, we need to find the volume of the water in the pool, and then we can calculate the weight.

Finding the Volume of Water

The volume of water in the pool can be calculated using the formula for the volume of a rectangular prism:

Volume = Base Area × Height

Given: - Height of the pool (h) = 30 cm - Side length of the square base (a) = 1 m = 100 cm

The base area of the pool is: Base Area = Side Length × Side Length = 100 cm × 100 cm = 10000 cm²

The volume of water in the pool is: Volume = Base Area × Height = 10000 cm² × 30 cm = 300000 cm³

Converting Volume to Liters

To make the calculation easier, let's convert the volume from cubic centimeters to liters: 1 liter = 1000 cubic centimeters

So, the volume of water in the pool is: Volume = 300000 cm³ = 300000 / 1000 = 300 liters

Calculating the Weight

The density of water is approximately 1 kg/liter, so the weight of the water in the pool is: Weight = Volume × Density = 300 liters × 1 kg/liter = 300 kg

Therefore, the weight of the inflatable pool with water is approximately 300 kilograms.
