Question

A water tank had length 9cm, breadth 7cm and
height 5cm. How cubic metre of water can it hold​

Answer 1

Correct question -

• A water tank had length 9cm, breadth 7cm and height 5cm. How cubic metre of water can it hold?

Solution -

• 3.15 cubic metre of water can the given water tank hold.

Given that -

• Length of water tank = 9 cm
• Breadth of water tank = 7 cm
• Height of water tank = 5 cm

To find -

• How many cubic metre of water can the given water tank hold?

Using concept -

• Formula to find volume of water tank. And it be according to its shape and by viewing it's unit as cubic. Volume = Length × Breadth × Height.

Putting the values -

↝ Volume = Length × Breadth × Height.

↝ Volume = 9 × 7 × 5

↝ Volume = 9 × 35

↝ Volume = 315 cm³

The question says that we have to find it in metres cube and we get it in centimetres cube. So, let's change the unit!

↝ 1 m = 100 cm

↝ 1 cm = 1/100 m

↝ 315/100

↝ 3.15 m³

• Henceforth, 3.15 m³ is the volume of the water tank that's means 3.15 cubic metre of water can the given water tank hold.

Answer 2

★ Question :

A water tank had length 9cm, breadth 7 cm and height 5 cm. How much cubic metre of water can it hold ?

ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ

★ Given :

• Length of tank = 9cm
• Breadth of tank = 7cm
• Height of tank = 5cm

ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ

★ To Find :

• Volume of tank

ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ

★Solution :

${\bold {\underline { •Volume \; of \; cuboid = Length \times breadth \times height }}}$

$\implies \sf { Volume = 9 \times 7 \times 5}$

$\implies \sf { Volume = 315 \; cm^3}$

$\implies \sf { In \; m^3 = 3.15 \; m^3}$
