one side of a flat board has an area of 874 square inches. if a pressure of 19 pounds per square inch of area is exerted on this side of the board, what is the total force, in pounds, exerted on this side of the board?

Explanation:

Step1: Recall the formula for force

The formula for force \(F\) is \(F = P\times A\), where \(P\) is pressure and \(A\) is area.

Step2: Substitute the given values

Given \(P = 19\) pounds per square inch and \(A=874\) square inches. Then \(F=19\times874\).
Calculate \(19\times874=(20 - 1)\times874=20\times874-874\).
\(20\times874 = 17480\) and \(17480-874=16606\).

Answer:

\(16606\)
