Answer:
x = SA - 72 /24
Step-by-step explanation:
SA=2(wl+hl+hw)
where,
- SA - surface area
- l - length
- w - width
- h - height
➟ SA = 2(wl+hl+hw)
Insert values
➟ SA = 2((6)(x)+(6)(x)+(6)(6))
Calculate
➟ SA = 2(6x + 6x + 36)
Add together
➟ SA = 2(12x + 36)
Multiply values in the bracket by 2
➟ SA = 24x + 72
Substract 72 from both sides
➟ SA - 72 = 24x
Switch sides
➟ 24x = SA - 72
Divide both sides by the coefficient of x
➟ 24x/24 = SA - 72/24
Calculate
➟ x = SA - 72 /24
