Answer 1

$\huge{\underline{\mathfrak{Solution:}}}$



$\sf{\large{\underline{\underline{Given \colon}}}}$

Length of the Bar = 25 cm
Breadth of the Bar = 18 cm
Height of the Bar = 6 cm


$\sf{\large{\underline{\underline{Explanation \colon}}}}$

Volume of Iron Bar
$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \implies \sf l \times b \times h \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \implies \sf25 \times 18 \times 6 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \implies \sf 2700 \: cm {}^{3}$

Weight of the bar
$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \implies \sf (2700 \times 100) \: gm \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \implies \sf 270000 \: gm \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \implies \sf 270 \:kg$

Answer 2

it is given that iron bar has dimensions 25,18,6 so

we know that volume of iron bar (cuboid) is l×b×h

volume of iron bar =25×18×6=2700cu.cm

1cucm weight 100g

2700cucm weights= 2700×100=270000g

or 270000/1000=270kg
