Question
A rectangular fish tank 35 cm long, 30 cm wide and 25 cm high is filled with water to a depth of 20 cm.Find the volume of water in the fish tank.Give your answer in litres.
Solution
To find the volume of the water in the fish tank, we need to use the formula for the volume of a rectangular prism, which is length x width x height.
Step 1: Identify the dimensions of the water in the tank. The length is 35 cm, the width is 30 cm, and the height (or depth of the water) is 20 cm.
Step 2: Multiply these dimensions together to find the volume in cubic centimeters. So, 35 cm x 30 cm x 20 cm = 21,000 cubic cm.
Step 3: Convert this volume to liters. Since 1 cubic cm is equal to 0.001 liters, we multiply 21,000 cubic cm by 0.001 to get the volume in liters. So, 21,000 cubic cm x 0.001 = 21 liters.
Therefore, the volume of the water in the fish tank is 21 liters.
