Find the volume of a cuboid whose
$(i i) .$ length $= 1.2 m$ , breadth $= 30 c m$ , height $= 15 c m$

Open in App

Solution

Given: Length of cuboid $= 1.2 m$
Breadth of cuboid $= 30 c m$
Height of cuboid $= 15 c m$

$∵ 1 m = 100 c m$
$\Rightarrow Length = 1.2 m = 1.2 \times 100 c m = 120 c m$

By using the formula,
Volume of a cuboid $= Length \times Breadth \times Height$
$= 120 \times 30 \times 15$
$= 54000 c m^{3}$

Hence, the volume of cuboid is $54000 c m^{3}$ .

Find the volume of a cuboid whose (ii). length =1.2 m, breadth =30 cm, height =15 cm

Given: Length of cuboid =1.2 m Breadth of cuboid =30 cm Height of cuboid =15 cm ∵1 m=100 cm ⇒Length=1.2 m=1.2×100 cm=120 cm By using the formula, Volume of a cuboid =Length×Breadth×Height =120×30×15 =54000 cm3 Hence, the volume of cuboid is 54000 cm3.
