Question

The length bredth and height of and iron trunk is 3m 1m 15 cm and 30 cm respectively find tje volume of the trunk

Answer 1

Answer:

1350 m cube

Step-by-step explanation:

Volume = Length× Breadth × Height

Given;

Length = 3 m

Breadth = 15 m

Height = 30 m

volume of the truck = 3 m × 15 m × 30 m

= 1350 m cube

Answer 2

Given: length, breadth and height of iron trunk i.e 3m, 1m 15cm & 30cm.

Need to find: The volume of the trunk?

⠀⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀

❍ Let's consider volume of the iron trunk as x.

⠀⠀⠀⠀

As we know that,

⠀⠀⠀⠀

$\begin{gathered}\star\:{\underline{\boxed{\frak{Volume_{\:(cuboid)} = Length \times Breadth \times height}}}}\\\\\\ \bf{\dag}\:{\underline{\frak{Putting\:given\:values\:in\:formula,}}}\\\\\\ :\implies\sf x = 3 \times 1.15 \times 0.30 \\\\\\ :\implies{\underline{\boxed{\frak{\purple{x = 1.035}}}}}\:\bigstar\\\\\end{gathered}$

⠀⠀⠀⠀

⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀

Therefore,

⠀⠀⠀⠀⠀

Volume of the iron trunk , x = 1.035m³.

⠀⠀⠀⠀⠀

$\therefore\:{\underline{\sf{Hence,\:Volume \: of \: the \: iron \: trunk \: is \: \bf{1.035m^3}\: \sf{respectively}.}}}$
