A fish tank has a length of 90 cm, a width of 50 cm, and a height of 40 cm. How many liters of water can it hold when it is completely filled? (Given: 1 m³ = 1000 liters, and 1 m = 100 cm)
Show answer & explanation
Correct answer: A
Explanation
Length = 90 cm, Width = 50 cm, Height = 40 cm
According to the formula: Volume = Length × Width × Height
Volume = 90 × 50 × 40 = 180,000 cm³
1 m³ = (100 cm)³ = 1,000,000 cm³
180,000 cm³ = 180,000 / 1,000,000 = 0.18 m³
Volume in liters = 0.18 × 1000 = 180 liters
