Question

There are two cuboidal boxes as shown in the given figure. Which box requires the less amount of material to make?

Answer 1

both will require the same as thier volume is same...hope its cleared..if doubts then comment

Answer 2

Solution :

i ) Dimensions of the Cuboid :

length ( l ) = 60 ,

breadth ( b ) = 40 ,

height ( h ) = 50

volume ( v ) = lbh

= 60 × 40 × 50

= 120000 cubic units ----( 1 )

ii ) Dimensions of the cube :

side ( a ) = 50 units

volume ( V ) = a³

V = ( 50 )³

V = 125000 cubic units -----( 2 )

Here ,

( 1 ) < ( 2 )

Therefore ,

First Cubiod requires less amount

of material .
