Acandy machine contains 120 spherical kids each candy is solid and has diameter of 0.25 in what is the total volume of the candies in the machine

We know that

for effects of the problem we will consider each candy  as if it were a cube of side equal to the diameter
[the volume of a cube]=b³
b=diameter> b=0.25 in
[the volume of a cube]=0.25³> 0.015625 in³

[total volume of the candies in the machine]=120*[volume of one candy]
[total volume of the candies in the machine]=120*[0.015625]
[total volume of the candies in the machine]=1.875 in³

the answer is 1.875 in³
