Question

Arun makes a cuboid of sides 5cm ,3cm and 2cm .How many such cuboids will he need to form a cube​

Answer 1

Answer:

900 cuboids to make a cube

Step-by-step explanation:

Arun makes a cuboid of sides 5cm ,3cm and 2cm .

Number of cuboids he will need to form a cube

$= \frac{volume \: of \: cube}{volume \: of \: cuboid}$

side of a cube= LCM of 5,3,2

=30cm

$= \frac{ {side}^{3} }{length \times breadth \times height}$

$= \frac{30 \times 30 \times 30}{5 \times 2 \times 3}$

$= \frac{27000}{30}$

=900

THEREFORE HE NEEDS 900 CUBOIDS TO MAKE A CUBE
