The amount of water that the tank can hold is #135,000l#.
The total surface area of the tank is #159m^2#.

Explanation:

To determine how many litres of water the tank can hold, we first calculate the volume according to the standard formula:

#V=lxxwxxd# where #V=#Volume, #l=#length, #w=#width, and #d=#depth.

#V=6xx5xx4.5#

#V=30xx4.5#

#V=135#

The volume of the tank is #135m^3#

Since #1m^3=1000l#,

#V=135xx1000#

#V=135,000#

The amount of water that the tank can hold is #135,000l#.

The total surface area of a cuboid is calculated as the sum of the areas of the six faces (considering the tank to be closed on all sides) and has the formula:

#TSA=2(l*w+w*d+d*l)#

#TSA=2([6*5]+[5*4.5]+[4.5*6])#

#TSA=2(30+22.5+27)#

#TSA=2xx79.5#

#TSA=159#

The total surface area of the tank is #159m^2#.
