48 cups can be filled with 18840 cubic cm of water.
Explanation:
Radius of cone = 5 cm
Height of the cone = 15 cm
Volume of cone = (1/3) π (r) (r) (h)
= (1/3) π (25) (15)
=125π
= 392.5 cubic cm
The volume of water available= 18840 cubic cm
Number of cups can be filled = 18840/392.5
= 48
48 cups can be filled with 18840 cubic cm of water
