Answer:
Step-by-step explanation:
The volume of the bigger rectangular tank is length × breadth ×height
V= l×b×h
V=80×60×40
V=192000
Volume of the smaller rectangular jar that will filled up the bigger one
V=l×b×h
V=20×10×15
V=3000
Then, the amount that will filled it up.
Bigger Volume / smaller volume
192000/3000=64
Therefore, 64 of the smaller volume will filled the bigger volume
