Question

a wooden rectangle box of 12 cm breadth,16 cm length and 8 cm height is to be made. How much wood is required ?​

Answer 1

Answer:

832cm² of woods

Explanation:

Wood Required = Surface area of box .

Surface area of box = 2[(lb)+(bh)+(hl)]

Given :

Length = 12cm

Breadth = 16cm

Height = 8cm

Solution :

Surface area = 2(12×16)+(16×8)(8×12))cm²

Surface area = 2[(192)+(128)+(96)]cm²

Surface area = 2 [416] cm²

Surface area = 832cm².

Hence , we need 832cm² wood to make that wooden box .

Answer 2

Answer:

832 cm square

Explanation:

given that
length=16cm

breadth =12 cm

height =8cm

surface area of box =2lb+2bh+2lh
                                  2*16*12+2*12*8+2*8*16

                                    832 cm square
