A closed metal box measure 30 cm x 20 cm x 10 cm. Thickness of the metal is 1 cm. The volume of the metal required to make the box is

1041 cm³

6000 cm³

4536 cm³

1968 cm³

Volume of cuboid =LxBxH

30x20x10 = 6000 cm³

Thickness =1

Internal volume...

Length =30-2x(thickness) =30-2= 28

Breadth =20-2x(thickness) =18

Height =10-2x(thickness) = 8

Volume =28x18x8 = 4032 cm³

External volume - internal volume = 6000 - 4032 =1968 cm³
Volume of metal required is1968c m³
