Step-by-step explanation:
volume of cylinder = πr2h diameter=7
radius=3.5
22/7×3.5×3.5×15
577.5cm3 (cube)
volume of cuboid= l×b×h
8×6×12
576cm3 (cube)
cuboidal pack =576cm3
cylinder pack = 577.5cm3
(1cm3=0.001 litre )
577.5-576=1.5cm
so you should buy the cylindrical pack
to get more soft drink
cylinder pack has 0.5775 litres of softdrink
cuboidal pack has 0.576 litres of softdrink
so if you buy cylindrical pack
you would get 0.0015 litres of extra softdrink.
for the same price.
enjoy your drink.
