I know this is kinda late, but...
You can solve this easily as long as you remember how to find the volume of a cube. v=a^3, when a means length. The length is 1/2 cm, or .5 cm.
So, v+.5^3, which equals .125 cm. Each cube has a that volume. Now, multiply that by how many actual cubes there are, 96.
96 * .125 = 12
Answer:
#1 is It could be another girl or it could be a boy
#2 is Its could be another boy or it could be a girl.
The diagram should look like this:
BB. BG
GB GG
#4 is 4
#5 is 1
#6 is there is 1/2 a change the baby can be a girl and a 1/2 change the baby can be a boy. For both of them to be girls; it would be 1/4 chance.
640/79=8...8
79 goes through 640 8 times
60 percent because 3/5= 0.6 and multiply by 100 its 60
