Answer: 
Step-by-step explanation:
The formula for calculate the volume of a cylinder is:

r is the radius of the cylinder and h is the height of the cylinder.
Given the diameter of 3 inches, calculate the radius of the cylinder with:
(Where d is the diameter)

Knowing the height and the radius, you can calculate the volume of the entire can of tuna:

As you want to know the cubic inches of tuna that are in the can (volume of tuna), and you know that the can is half full, then:

1/2 * 1/4 = 1/8
3/8 * 2/3 = 1/4 same for back left fin
2/5 *1/2 = 1/5
2/3 *1/2 = 1/3
1/4 + 3/4 = 8/8
2/3 +1/6 = 5/6
4/5 +1/5 = 4/4
1/4 +1/5 = 9/20
front/back right fin = 3/8
x+ 1 2/3..... = 4/5
You can't.
There isn't enough evidence/proof to prove the length of each side.<span />
