Question #efb68

Answer 1

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`.
