Answer:
40
Step-by-step explanation:
The volume of the cylindrical box is given as 904.32 cm³, the diameter as 12cm
The volume of a cylinder is given by the formula
V = π · r² · h where r is the radius and h is the height
The radius of the given box is 12/2 = 6 cm and we use π = 3.14
Plugging in known values we get
3.14 · 6² · h = 904.32
113.04 h = 904.32
h = 904.32 / 113.04 = 8 cm
Each CD is 0.2 cm thick so we can fit a total of
8 / 0.2 = 40 CDs
