Question

What is the volume of water in a fish tank 100cm length 50 cm width and 40 cm high?

Answer 1

200 litre/liter

Explanation:

First.... find out the volume of the fish tank
Volume of cuboid`=lxxbxxh`
Volume of cuboid`=100cmxx50cmxx40cm`
volume of cuboid`=200000cm^3`
Change it into `m^3`
`1m=1x100cm`
`1m^2=1xx100xx100cm^2`
`1m^3=1xx100xx100xx100cm^3`
Similiarly
volume of cuboid`=0.2m^3`
Now...
`m^3=1000` liter/litre(depending on where you are in the world)
`m^3xx0.2=1000xx0.2=1000xx0.2` litre/liter
`0.2m^3=200` liter/litre

Answer 2

`"volume "=200" litres"`

Explanation:

`"assuming fish tank is "color(blue)"cuboid in shape"`

`• " volume "="length "xx"width "xx"height"`

`rArr"volume" =100xx50xx40`

`color(white)(rArr"volume ")=200000" cm"^3`

`["note "1" litre "=1000" cm"^3]`

`rArr"volume" =200000/1000=200" litres"`
