Answer :
Taking the quotient between the mass of the box and the mass of a single ball, we conclude that there are 64 balls in the box.
How many balls are in the box?
We want to find the number of balls in a box weighing 10 kg, we need to convert the weight of one ball to kilograms and then divide the total weight of the box by the weight of one ball.
Given that the weight of one ball is (156 + 1/4) g, we can convert it to kilograms:
Weight of one ball = (156 + 1/4) g = (156.25) g = 0.15625 kg
Next, we divide the total weight of the box (10 kg) by the weight of one ball (0.15625 kg):
Number of balls = 10 kg / 0.15625 kg = 64
there are 64 balls in a box weighing 10 kg.
