To calculate the volume of the fish tank, you need to multiply the length, width, and height of the tank. Here are the steps to find the volume of a fish tank that is 15cm by 30cm by 10cm:

Step 1: Write down the given dimensions of the fish tank:
Length = 15 cm
Width = 30 cm
Height = 10 cm

Step 2: Use the formula for calculating the volume of a rectangular prism:
Volume = Length × Width × Height

Step 3: Substitute the given values into the formula:
Volume = 15 cm × 30 cm × 10 cm

Step 4: Perform the multiplication:
Volume = 4500 cm^3

Therefore, the volume of the fish tank is 4500 cubic centimeters or cm^3.
