Volume Units: A shape consisting of several shapes (requiring the same formula)

To solve this problem, we'll follow these steps:

• Step 1: Calculate the total volume of 3 cuboids in cubic meters.
• Step 2: Convert this volume from cubic meters to cubic centimeters.

Let's go through each step:

Step 1: The volume of one cuboid is given as $130 \, m^3$. Since we need the volume of 3 such cuboids, we multiply:

$3 \times 130 \, m^3 = 390 \, m^3$

Step 2: To convert cubic meters to cubic centimeters, we use the conversion factor: $1 \, m^3 = 1,000,000 \, cm^3$. Therefore,

$390 \, m^3 = 390 \times 1,000,000 \, cm^3 = 390,000,000 \, cm^3$.

Therefore, the volume of 3 cuboids in cubic centimeters is $\mathbf{390,000,000 \, cm^3}$.

To solve this problem, we'll follow these steps:

• Step 1: Convert the volume of one bottle from liters to milliliters.
• Step 2: Multiply the volume of one bottle by the number of bottles.

Step 1: Each bottle holds 1.8 liters. Since 1 liter is equal to 1000 milliliters, we convert 1.8 liters to milliliters:

$1.8 \text{ liters} \times 1000 \, \text{milliliters/liter} = 1800 \, \text{milliliters}$.

Step 2: Calculate the total capacity for 3 bottles:

$1800 \, \text{milliliters/bottle} \times 3 \, \text{bottles} = 5400 \, \text{milliliters}$.

Therefore, the total capacity of 3 bottles is $5400 \, \text{milliliters}$.
