Two similar refrigerators contain 20kg and 35kg of food items. If the height of the larger refrigerator is 1.5 metres, calculate the height of the smaller one to 3 s.f

Answer 1

To find the height of the smaller refrigerator, we can use the concept of proportionality. Since the amount of food items is directly proportional to the height of the refrigerator, we can set up the following proportion:

20kg / x = 35kg / 1.5m

Solving for x (the height of the smaller refrigerator):

x = (20kg * 1.5m) / 35kg
x = 0.8571m

Therefore, the height of the smaller refrigerator to 3 significant figures is 0.857m.
