Answer:
1/12 of the pizza
Step-by-step explanation:
A box (cube) has all equal edges or sides (s), thus the volume (v) of the cube is:

So since each side or edge around is 3 in, then the length around the square bottom of the box = 4×3 = 12 in
6 inches because area= length times width and 6 times 8= 48 inches
