Question 34 Mensuration Exercise 18.4

A car has a petrol tank 40 cm long, 28 cm wide, and 25 cm deep. If the fuel consumption of the car averages 13.5 km per liter, how far can the car travel with a full tank of petrol?

Answer:

Given,

Capacity of car tank = 40 cm × 28 cm × 25 cm = (40 × 28 × 25) cm3

= (40 × 28 × 25)/1000 litre [[∵ 1000 cm3 = 1 litre]]

Average fuel consumption of car = 13.5 km per liters

Then, the distance traveled by car is given by

= 14 × 27 km

= 378 km

Hence, the car can travel 378 km with a full tank of petrol.
