3 balls whose weights are 1 kg,1.5 kg and 2 kg are put in a bag. Then, a cube of weight 0.5 kg is added. On top of that, 10 kg of sand is poured into the bag. What is the final weight of the bag (in kg)?
Total weight of 3 balls=(1+1.5+2)㎏=4.5㎏
Weight of bag=Weight of 3 balls+weight of cube+weight of sand
=(4.5+0.5+10)㎏=15㎏
