Question

A cubical tank with an edge length of 20 cm is filled with 3.75 liters of water. How much more water is needed to fill the tank completely? Give your answer in liters.

Answer 1

Answer:

4.25 Liters

Step-by-step explanation:

Edge of Cubical tank

= 20 cm

= 20 (0.01 m)……………..1 meter = 100 cm

= 0.2 m

Volume of Tank

= ( Edge ) ^ 3

= ( 0.2 m ) ^3

= 0.008 m^3

= 8 liters…………….. 1 m^3 = 1000 Liters

Volume required to fill the tank

= 8 - 3.75

= 4.25 Liters
