Question

Select the correct answer.

Answer 1

Answer:

Tank 1 :

height = 2x-2

length = 4x

y = l w h

  = (4x) (x) (2x-2)

  = (4$x^{2}$) (2x-2)

  = 8$x^{3}$-8$x^{2}$

Tank 2:

height = 6x

length = 2x-1

y = l w h

  = (2x-1) (x) (6x)

  = (2$x^{2}$-x) (6x)

  = 12$x^{3}$-8$x^{2}$

I think it is the second option but I am not sure because the picture is very unclear. Do double check with the answers I have worked out.

Hope this helps.
