​

Answer 1

Answer:

length = 65 cm

breadth = 45cm

high = 10 cm

Answer 2

Solution :

A petrol tank has the following dimensions :

> Length = 65 cm

> Breadth = 45 cm

> Height = 10 cm

Volume of the tank :

> [ Length ] * [ Breadth ] * [ Height ]

> 65 * 45 * 10 cm^3

> 28800 cm^3 .

The capacity of the tank is 28800 cm^3 .

1 cm^3 = 0.001 liters

> 28.8 liters .

The cost of petrol is Rs. 69.8 per liter.

Total cost of filling the tank :

> Rs. 69.8 * 28.8

> Rs. 2010.24

This is the required answer.
