Question

the outer dimensions of a closed wooden box are 16 cm by 12 CM by 8cm. Thickness of the wood is 1cm. Find the total cost of the wood required to make box ,if 1cmcube of wood costs rupees 2.50 .​

Answer 1

Given:-

outer dimensions = 16 * 12 * 8

so outer volume of wooden box = 1536 cm3

the width of the box = 1cm

cost of 1cm3 = 2.50

solution :-

outer volume = 1536 cm3

width = 1cm

the inner dimensions of box are

(16 - 2)* ( 12 - 2 )* ( 8 - 2)

14 * 10 * 6

so the inner volume of wooden box

= 14 * 10 * 6

= 840cm3

now the total volume of wood to make required box is

( outer volume - inner volume)

(1536 - 840)

696cm3

the cost of 1cm3 cube wood

= 2.50 Rs

so the total cost to make wooden box

= 696 * 2.50

= 1740 Rs

hope it's help ✌✌
