Answer 1

Amount of water tank has

= 500,000 cm^3

= 500,000 (1 cm)^3

= 500,000 (0.01 m)^3 …………………..[1 cm = 0.01 m]

= 500,000 x 0.0000001 m^3

= 0.5 m^3

= 0.5 (1000 liters)………………………[1 m^3 = 1000 liters]

= 500 liters

Total amount of water drawn out of the tank

= 110 ( Kitchen and Bathroom) + 100 (Car wash) + 100 (Washing terrace )

= 310 liters

Amount of water left in the tank

= 500 - 310

= 190 liters
