Question

A topless wooden box is of 15 cm
length, 12 cm breadth, 5 cm height, Area
of the wood sheet required to make that
box is​

Answer 1

ANSWER = 450 cm²

length = 15 cm

breadth = 12 cm

height = 5 cm

total surface Area = 2( LB + BH + LH )

= 2 ( 180 + 60 + 75 )

= 2 ( 315 )

= 630 cm²

since it is topless , one LB is to be removed ,

= 630 - 180

= 450cm²

ie, 450 cm² wooden sheet is required
