The amount of water that the tank can hold is 135,000l.
The total surface area of the tank is 159m2.

Explanation:

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

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

V=6×5×4.5

V=30×4.5

V=135

The volume of the tank is 135m3

Since 1m3=1000l,

V=135×1000

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(lw+wd+dl)

TSA=2([65]+[54.5]+[4.56])

TSA=2(30+22.5+27)

TSA=2×79.5

TSA=159

The total surface area of the tank is 159m2.
