Question

external dimension of a closed wooden cuboidal Box length 30 cm breadth 25 cm height 20 CM if the thickness of the wood is 2cm all around find the volume of the wood contained cuboidal box formed

Answer 1

see the length,

30cm length but thickness is 2cm then 2cm less from starting point of length and 2cm less from ending point of length

so, the length is 26cm

similarly, breadth = 21cm and height = 16cm.

L = 26cm,

B = 21cm,

H = 16cm.

volume of cuboidal = L*B*H

volume of cuboidal = 26*21*16

volume of cuboidal = 8736cm³
