Answer:
19
Step-by-step explanation:
Formulas for a rectangular prism:
Volume of Rectangular Prism : V = lwh.
Surface Area of Rectangular Prism: S = 2(lw + lh + wh)
Space Diagonal of Rectangular
Prism: (similar to the distance between 2 points) d = √(l2 + w2 + h2)
It would be: 2(p + 1) = 18
= 2p + 2 = 18
= 2p = 18 - 2
= 2p = 16
= p = 16/2
= p = 8
In short, Your Answer would be 8
Hope this helps!
