Answer: hello your question lacks the required diagram attached below is the diagram
answer : Â 29528.1 Â N/m^2
Explanation:
Given data :
dimensions of tank :
Length = 5-m
Width = 4-m
Depth = 2.5-m
acceleration of tank = 2m/s^2
Determine the maximum gage pressure in the tank
Pa ( pressure at point A ) Â = s*g*h1
  = 10^3 * 9.81 * 3.01
  = 29528.1  N/m^2
attached below is the remaining part of the solution
