Let the length of cobiod be 3x
breadth be 4x
height be 5x
and,volume of cuboid Is=3840 cu.cm
then,
volume of cuboid=3840
l×b×h =3840
3x ×4x ×5x=3840
60x=3840
x=3840÷60
x=64
now,
length=3x=3×64=192cm
breadth be 4x
height be 5x
and,volume of cuboid Is=3840 cu.cm
then,
volume of cuboid=3840
l×b×h =3840
3x ×4x ×5x=3840
60x=3840
x=3840÷60
x=64
now,
length=3x=3×64=192cm
