Answer 2

Answer: Capacity = 29.4 litre of milk. Cost of 29.4 litre = ₹ 352.80

Step-by-step explanation: Length of tank = 4.2 m

                                           Breadth of tank = 3.5 m

                                             Height of tank = 2 m

                                   ∴ Capacity of tank = LENGTH × BREADTH × HEIGHT

                                 = 4.2 m × 3.5 m × 2 m

                                = 29.4 litre.

                            Cost of milk per litre = ₹ 12.

                           Cost of 29.4 litre of milk = ₹ 12 × 29.4 litre

                                         =  ₹ 352.80
