Correction:
Delete6S) Divide 12 by 4 cm On one side of the bigger cube you can have 3 cubes fitting to get the total number of cubes in all the bigger cube multiply 3X3X3=27 cubes fitting in altogether
4S) Depth = 2.4 m
5S)Height is 10cm: Solution: Total Volume of tank= 5000 Cubic cm=5 litres
Note this: 5 litres =25 cms deep
2 litres= ? cm deep
Do this simple fraction: Height= 2X25/5=10 cms
Marks= 0/5 marks
