You will use the formula for the volume of the sphere to find the volume of one ice cube.
I will use 2 cm as the radius.
V = 4/3 x pi x r^3
4/3 x 3.14 x 2^3
V = 33.49 cubic cm
The volume of 1 ice cube is approximately 33.49 cubic cm, so 6 would be 6 x 33.49.
The volume of 6 ice cubes is approximately 200.94 cubic centimeters.
