Question

A rectangular container is 80 cm long and 78 cm wide. It contains 50 litres of ink when it is 80% full. Find the height of the container. Round your answer to 2 decimal places if necessary.

Answer 1

Answer:

Step 1 : Volume of the container = Volume of the ink ÷ 70% = 50 × 100 ÷80 = 62.5 litres.

Step 2: Convert 62.5 liters to cm3. 62.5L = 62500 cm3.

Step 3: The height of the container = 62 500 ÷ 80 ÷ 78 = 10.02 cm
