Question

A fish tank was 30cm long, 50cm wide and 40 cm high. It was half-filled ith water. What volume of water has not been filled?​

Answer 1

Answer:

Volume of the tank not filled with water =30000cm

Step-by-step explanation:

Volume = length ×wide ×hight

therefore, volume of the fish tank = (30×50×40)cm

volume = 60000cm

Since half of the tank was filled with water the volume of water has not been filled

= 1/2 of 60000cm

=1/2×60000cm

=60000÷2×1

=30000×1

=30000cm
