Question

Fruit juice is packed in cubical packet of sides 5 cm by 4 cm by 6 CM assuming that 1/6 of the box is empty how much juice does each packet contains how much juice has been packet in 100 such packets

Answer 1

volume of the juice packet = lbh = 5×4×6=120cm³
box that is empty = 1/6
box which is filled = 5/6
volume of juice in box = 120×5/6 = 100cm³
•°•, juice in 100 such packets = 100×100 = 10000cm³ or 10litre (1000cm³=1l)

HOPE HELP YOU

Answer 2

so the volume of the cuboid

$volume=l×b×h$

$volume \:of \:packet=5×4×6=120cm^2$

$since,1/6 \:of \:packet \:is \:empty$
$so \:5/6 \:of \:juice \:packet \:is \:filled$

$now \:volume \:would \:be \:=$
$5/6*120cm^2=100cm^2$

$since, \:the \:is \:packed \:in \:100 \:packet$

$amount \:of \:juice \:they \:contain$

$=100×100=10000cm^2$

$since \:1000 \:liters \:=1 \:cm^2$

$amount \:of \:juice \:is \:10000/1000$

$so \:10 \:liters \:of \:juice \:is \:packed$
