Question

Дуремалу для разведения пиявок нужен аквариум, вмещающий не менее 390 л воды. В магазине есть аквариум с измерениями 90 см, 60 см и 75 см. Подойдёт ли он аптекарю. (1 л - 1 дм в кубе)

Answer 1

Размер аквариума 9 на 6 на 7,5 дм

его объём 9*6*7,5=405 куб.дм = 405 л, что больше требуемого, подойдёт

Answer 2

90*60*75=405000 см.. т.е. 405 дм
405 больше 390 значит подойдет

Answer 3

Can an aquarium with dimensions 90 cm x 60 cm x 75 cm hold at least 390 liters of water?

To determine if the aquarium with dimensions 90 cm x 60 cm x 75 cm can hold at least 390 liters of water, we need to calculate its volume.

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

Volume = Length x Width x Height

Given the dimensions of the aquarium: - Length = 90 cm - Width = 60 cm - Height = 75 cm

Let's calculate the volume:

Volume = 90 cm x 60 cm x 75 cm

Converting the dimensions to decimeters (1 liter = 1 cubic decimeter): - 1 cm = 0.1 dm

Volume = (90 cm x 0.1 dm/cm) x (60 cm x 0.1 dm/cm) x (75 cm x 0.1 dm/cm)

Simplifying the equation: Volume = 9 dm x 6 dm x 7.5 dm

Calculating the volume: Volume = 405 dm³

Based on the calculation, the volume of the aquarium is 405 dm³, which is greater than 390 liters. Therefore, the aquarium with dimensions 90 cm x 60 cm x 75 cm can hold at least 390 liters of water.
