Question

A cuboidal petrol tank is $30$ cm long, $30$ cm wide and $1$ m $60$ cm high. It has petrol upto a height of $40$ cm. How much more cu cm of petrol can the tank contain?

• A. $3,600$ cc
• B. $1,440$ cc
• C. $1,08,000$ cc
• D. None of these

Answer 1

Answer: (C)

$1,08,000$ cc

Volume of cuboid$=length\left(l\right)\times breadth(b\times height(h)$

The dimensions of cuboidal petrol tank is

$l=30cm$

$b=30cm$

$h=1m60cm=100+60=160cm(1m=100cm)$

Volume$=30\times 30\times 160=144000c{m}^3$

The dimensions of petrol is

$l=30cm$ (It is not given but it will be the same as tank because petrol is liquid and it will take the shape of tank)

$b=30cm$ (It is not given but it will be the same as tank because petrol is liquid and it will take the shape of tank)

$h=40cm$

Volume$=30\times 30\times 40=36000c{m}^3$

$Theamountpetrolthetankcancontain=volumeofcuboidalpetroltank-volumeofpetrol$

$=144000-36000$

$=108000c{m}^3$
