Question

a cubical tank with an edge of 20 cm is filled with 3.75 liters of water. how much more water needed to fill the tank completely . give your answer in liters.

Answer 1

Answer:

4.25 litres

Step-by-step explanation:

Given Edge = 20 cm.

Volume of cubical tank = 20³

                                      = 8000 cm³.

                                      = 8000 * 0.001

                                      = 8 litres.

Given, Water filled in cubical tank = 3.75 litres.

Hence, Water needed to fill the tank = 8 - 3.75

                                                            = 4.25 litres.

Hope it helps!

Edge of cubical tank,A=20cm

Volume of cubical tank=A³=20×20×20=8000 cm³=8litre
