Answer:

The answer to your question is:

Explanation:

Data

V = 924 cm³

dimensions = 4cm, (x + 1) cm, (x + 11) cm

Factorize x² + 12x - 220 = 0

Find the prime factors of 220

220 2

110 2

55 5

11 11

1

Find two numbers that added give +12, these numbers are + 22 and -10

x² + 12x - 220 = ( x + 22) ( x - 10)

x 1 = -22 x2 = 10

The result -22 could not be a solution because lenght is not negative. Then x = 10

= 4 ( 10 +1) ( 10 + 11)

= 4 ( 11 ) ( 21)

= 924 cm³
