Answer:
26 Cups can be put in the dispenser
Step-by-step explanation:
Given that:
height of cup = 10 cm
each cup adds = 0.8 cm to stack
Dispenser height = 30 cm
We have to find number of cups that can fit into dispenser:
When the first cup will be placed into the dispenser,
Available length will be = 30 - 10 = 20 cm
Now each next cup will add 0.8 cm so:
20 cm will have = 20/0.8 cups
20 cm will have = 25 cups
And the total (30 cm) will have = 26 cups
