(4m)

A tank with a base measuring 60 cm by 10 cm had two leaks at 400 cm

(4m)

Volume of water leaked per minute

= 400 + 300

= 700 cm

Volume of water leaked in 6 minutes

= 6 x 700

= 4200 cm

Base area of the tank

= 60 x 10

= 600 cm

Decrease in height of water

= 4200 ÷ 600

= 7 cm

Height of water in the tank after 6 min

= 15 - 7

= 8 cm

Answer(s): 8 cm
