area of the box is
(A) 420 dm
(B) 452 dm
(C) 451 dm

Answer 1

Step-by-step explanation:

Unit of pressure: pascal (Pa)

Pressure is the amount of force applied perpendicular to the surface of an object per unit area and the for it is p (or P). The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m2, or kg·m−1·s−2).
