If I had two turtles that are 45cm long and they need water how big will my cage be and the water must be 56 inches long?

Your cage would be half a meter long.

Nope. With 56 inches of water, you'll need a cage that's about 5 feet long or almost 2 meters long.

To determine the size of the cage you would need for your two turtles, you would first need to calculate the total space required for the turtles and the water. Here are the steps to follow:

1. Calculate the total length required: Since you have two turtles that are 45cm long each, you need to add their lengths together. The total length required would be 45 cm + 45 cm = 90 cm.

2. Convert the required length to inches: To ensure consistency, you need to convert the length from centimeters to inches since the water length is given in inches. There are 2.54 centimeters in an inch. So, 90 cm รท 2.54 = 35.43 inches.

3. Determine the size of the cage: Since the water must be 56 inches long, you need to make sure the cage accommodates this length. If the turtles also need some space to move around, you should consider providing additional space. Based on the information provided, the cage should be at least 56 inches long to meet the required water length.

It is important to note that this calculation only considers the length of the turtles and the water element. Other factors, such as the width and height of the cage, would also need to be considered to provide suitable living conditions for the turtles.
