Question

the length of cuboid is 12 cm and breadth 9 cm and height 5 cm find the total surface area of cuboid and volume of cuboid in explain with diagram ​

Answer 1

TSA of cuboid=426,volume=540

l=12,b=9,h=5.

TSA of cuboid=2(lb+bh+lh)

=2(12×9+9×5+12×5)

=2(213)

=426cm2

volume of cuboid=lbh

=12×9×5

=540cm3

Answer 2

$\huge{\tt{\underline{Given:-}}}$

• Length of cuboid :- 12 cm

• Breadth of cuboid:- 9 cm

• Height of the cuboid:- 5 cm

$\huge{\tt{\underline{To\:find:-}}}$

• Total surface area of cuboid

• Volume of cuboid

$\huge{\tt{\underline{Solution:-}}}$

★ Total surface of cuboid = 2(lb+bh+hl)

So,

=2(12×9+9×5+5×12)

=2(108+45+60)

=2(213)

${\boxed{\bf{426\:cm^{2}}}}$

★ Volume of cuboid= l×b×h

= 12×9×5

= 60× 9

${\boxed{\bf{540\:cm^{3}}}}$
