18 inches.

Step-by-step explanation:

We have been that Mick has has just purchase a new printer that came in a box with a surface area of 1,781.7 square inches. The box is 26.5 inches long and 9.3 inches wide. We are asked to find the height of the box.

We will surface area of cuboid formula to solve for the height of the box.

SA=2(lh)+2(hw)+2(wl) , where,

h = Height,

l = Length,

w = width.

Upon substituting our given values in surface area formula, we will get:

$1781.7=2(26.5\cdot h)+2(h\cdot9.3)+2(9.3\cdot26.5)$

1781.7=71.6h+492.9

71.6h+492.9=1781.7

71.6h+492.9-492.9=1781.7-492.9

71.6h=1288.8

$\frac{71.6h}{71.6}=\frac{1288.8}{71.6}$

h=18

Therefore, the height of the box is 18 inches.
