Question

A glass aquarium is in the form of a rectangular parallelepiped with dimensions 50cm by 100cm, and its depth is 30cm.How many liters of water will it hold?

Answer 1

Hello! To find the number of liters of water, we have to calculate the volume of the parallelepiped:

The formula of the volume is:

Now that we know the volume, we have to convert cm³ to liters.

For this, we must remember:

1cm³ = 0.001 liter

Multiplying by rule of three, we will obtain:

`\begin{gathered} 1\cdot x\text{ = 150,000 }\cdot\text{ 0.001} \\ x\text{ = 150 liters} \end{gathered}`
