Question

How many planks of size 2 cm × 25 cm × 8 cm × can be prepared from a wooden block 5 cm × long, 70 cm broad and 32 cm thick assuming that there is no wastage solve it.Co?

Answer 1

$\textbf{ Hello Mate! }$

No. of plank produced = Volume of Wooden Block / Volum of 1 plank.

Volume of wooden block =

$= (5 \times 70 \times 32) {cm}^{3} \\ = 11200 \: {cm}^{3}$

Volume of plank =

$= (2 \times 25 \times 8) {cm}^{3} \\ = 400 \: {cm}^{3}$

No. of wooden plank required =

$= \frac{11200}{400} \\ = 28$

Concept : Volume of cuboid is taken out by multiplying length, breadth and height of cuboid.

$\boxed{ \textsf{ \red{ 28\:wooden\:planks\:can\:be\:produced }}}$

Have great future ahead!

Answer 2

Dimensions of the wooden block = Length = 70 cm , Breadth= 32 cm , Height = 5 cm


Dimensions of the plank = Length = 25 cm , Breadth = 8 cm , Height = 2 cm


Volume of the Wooden block = lbh = 70*32*5 = 11200 cm² .

Volume of plank = lbh = 2*25*8 = 400 cm².

No of planks = volume of Wooden block/Volume of plank = 11200/400 = 28 .

#Hence the number of planks required is 28.
