Question

Substitute the given values into the given formula and solve for the unknown variable. If​ necessary, round to one decimal place.

S=4LW+2WH​; S=138​, L=9​, W=3. ​(Surface area of a special rectangular​ box)
H=

Answer 1

Explanation:

We have the formula for the surface area of a rectangular box given by:

S = 4LW + 2WH

Substituting the given values, we get:

138 = 4(9)(3) + 2(3)H

Simplifying, we get:

138 = 108 + 6H

6H = 138 - 108

6H = 30

H = 30/6

H = 5

Therefore, the value of the unknown variable H is 5.
