Answer

202 square inches

Work Step by Step

We are given the formula $SA=2HL+2LW+2HW$, which measures the surface area of a rectangular box in square units. In this example, the dimensions of the box are 5 inches by 4 inches by 9 inches. So, we can plug in $H=5$, $L=4$, and $W=9$ into the equation. $SA=2(5)(4)+2(4)(9)+2(5)(9)=40+72+90=202$ square inches
