The dimensions of a water tank are: height = 3x + 5 inches, length = 2x – 1 inches, and width = 4x + 4 inches. If the volume of the water tank is 396 cubic inches, what is the value of x?

x = inches

Volume=hlw

396 = (3x + 5)(4x + 4)(2x-1)

24x^{3}+52x^{2}+8x-416=0

4(x-2)(6x^{2}+25x+52)=0

x = 2
