    Answer:

    70cm

    Step-by-step explanation:

    ,

    Since, both of the tank posses the same quantity of water then there volume is the same thing

    For rectangular base

    Volume= (Lenght × breadth × hheight)

    If we substitute values

    Lenght= 80 cm

    Breadth= 70 cm

    height= 45 cm

    Volume= 80cm × 70cm × 45cm

    Volume= 252000cm^3

    For square base

    Volume= (side)^2 × height

    side =60cm.

    But volume of square base= volume of

    rectangular base

    252000cm^3= 60^2 × height

    Height= (252000cm^3)/(60^2 )

    Height= 70 cm

    Hence, the second tank is 70 cm deep
