Question

calculate the mass of a water in a tank of length 50 cm breadth 40 cm and height 10 cm. if the mass of 1³ of water is 1 gram​

Answer 1

Answer:

20,000 grams, I think

Explanation:

Answer 2

Explanation:

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}}

∴Volumeoftankis20000cm

_______________________

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}}

∴Massoftankis20kg
