Its 5

1 mark in 1 test.Keep on adding 5 marks for next tests.After 2 marks will be 6,after 3 marks will be 11,after 4 tests marks will be 16 which makes average of 4 so 3 more tests required

Its 10m

There will be 1000 cubes of 1 decimeter.Keep on adding vertically , simply multiply 1000 with 1 decimeter.1000 * 0.1 m = 100 meter
