Question

A block of wood is in the form of a cube whose edge is 3m. How many rectangular pieces of size ,30cm*20cm*15 can be cut from the block, if there is no wastage of wood

Answer 1

$\huge SOLUTION:$

Volume of each piece
$= lbh$
$= 30 \times 20 \times 15$
$= 9000 {cm}^{3}$

Volume of Wooden Block
$= {a}^{3}$
$= {3}^{3}$
$= 27 {m}^{3}$
$= 27000000 {cm}^{3}$

Therefore, Number of Pieces
$= \frac{27000000}{9000}$
$= 3000 \: pieces$

Answer 2

Answer:

3000 cuboids can be made from the given cube.

Step-by-step explanation:

3 m = 300 cm, since 1 m = 100 cm

Volume of cube = N x Volume of cuboid  

This is the formula for this question where N stands for number of cuboids.

Just substitute the values

L³ = N x l x b x h

300 x 300 x 300 = N x 30 x 20 x 15

300 x 300 x 300/30 x 20 x 15 = N

N = 3000

Therefore 3000 cuboids can be made from the given cube.
