Question

Calculate the mass of water in a tank of length 50 cm, breadth 40 cm and height 10cm,if the mass of 1cm3 of water is 1g

Answer 1

To find the capacity of the tank.

Volume of tank =length×breath×height

Volume =40×60×50

=120000cm

3

⇒convert cm

3

into ml

We get,

⇒120000cm

3

=120000ml

⇒convert mlto l

We get,

120000ml=120l

Amount of water needed 120−50=70 liter

Hence,

70 liter of water is needed to fill the tank.

GivieN :

Length of tank (L) = 50 cm

Breadth of tank (B) = 40 cm

Height of tank (H) = 10 cm

To FinD :

Mass of tank if 1 cm³ of water is 1 gram.

SolutioN :

Use formula for the volume of cuboid

⇒Volume = length * breadth * height

⇒V = LBH

⇒V = 40 * 10 * 50

⇒V = 2000 * 10

⇒V = 20000

\underline{\sf{\therefore \: Volume \: of \: tank \: is \: 20000 \: cm^3}}

∴Volume of tank is 20000cm

3

_______________________

Now, for calculating mass of tank.

⇒1 cm³ volume = 1 gram

⇒20000 cm³ volume = 1 * 20000 gram

⇒Mass = 20000 grams

Convert Grams to Kilo Grams

⇒Mass = 20000/1000

⇒Mass = 20

\underline{\sf{\therefore \: Mass \: of \: tank \: is \: 20 \: kg}}

∴Mass of tank is20kg.
