Question

A wooden plank is 140cm long, 60cm broad and 40cm thick. It is cut into 336 cubes . Find the volume of each of the smaller cubes

Answer 1

l = 140 cm , b = 60 cm , h = 40 cm

volume of plank = l×b× h
= 140×60×40
= 336000 cm

volume of smaller cubes = volume of plank ÷ number of cubes
= 336000÷336
= 1000 cu.cm

therefore, volume of each of the smaller cubes is 1000 cu.cm

Answer 2

_____________________________

❥ GIVEN :

• A wooden plank is 140cm long, 60cm broad and 40cm thick. It is cut into 336 cubes.

_____________________________

❥ TO FIND :

• The volume of each of the smaller cubes.

_____________________________

❥ ANSWER :

$\red \star \: \: \sf{volume \: of \: plank =l \times b \times h }$

$= \sf{140 \times 60 \times 40}$

$= \sf{336000 \: cm}$

volume of smaller cubes

$\sf \tiny{{ } \huge = \frac{volume \: of \: plank}{number \: of \: cubes} }$

$\huge \sf{ = \frac{ \cancel{336000} {}^{ \: 1000} }{ \cancel{ 336}} }$

= 1000³ cm

_____________________________

❥ FINAL ANSWER :

.'. Therefore, volume of each of the smaller cubes is 1000³ cm

================================

these are the correct steps !!!
