Answer:

x = 4 ± \sqrt{5}

Step-by-step explanation:

to find the solutions equate the quadratic to zero

x² - 8x + 11 = 0 ( subtract 11 from both sides )

x² - 8x = - 11

solve using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 4)x + 16 = - 11 + 16

(x - 4)² = 5 ( take square root of both sides )

x - 4 = ± \sqrt{5} ( add 4 to both sides )

x = 4 ± \sqrt{5}

Answer: Wait a minute, Is the answer is 144 cubic centimetres?

Step-by-step explanation: So this is the given formula volumebox = width x length x height. Measure any two sides (length, width or height) of an object or surface in order to get a two-dimensional measurement, then multiply the width, length, and the height: 12*6*2=144 cm^3.
