Answer: 8.94
Explanation:
By common logic, you can say that l=8, w=4 and h=2.
The diagonal of the base can be found by using Pythagorean Theorem.
Pythagorean Theorem: a²+b²=c²
Since we know the a and b of the base, we can find c, the diagonal.
a and b is the l and w. We can use the equation to find c.
8²+4²=c²
64+16=c²
80=c²
c=√80
c≈8.94
The diagonal is approximately 8.94
