Question

When a box contains 50 identical balls, it has a mass of 13.9 kg. The empty box has a mass of 400 g. Find the mass of each ball in kilograms.

Answer 1

Answer:

approx 1.5

Step-by-step explanation:

if we convert 13.9 kg into gram it will 13900

13900/50 =273

one ball cost 273

so it will contain 1.5 ball

Answer 2

Answer:

0.27kg  ( or 270g)

Step-by-step explanation:

mass of the box with 50 balls = 13.9 kg

mass of the box alone             = 0.4kg    ( 400g given )

=> mass of 50balls alone = 13.9kg - 0.4kg

                                          = 13.5 kg

so, the mass of 1 ball = 13.5 kg / 50

                                   = 27/100 kg

                                   = 0.27kg  ( or 270g)
