Question

Parikishit nakes a cuboidal of plastine of sides 5cm,2cm,5cm . How many such cuboids will need to form a cube? ​

Answer 1

Step-by-step explanation:

First the length,breadth,height of the cuboid are 5,2,5cm respectively.

Then it's total surface area=

2(LBplusBHplusHL)

2(5.2plus2.5plus5.5)

2(10plus10plus25)

2.45

90cm

Then 90 is not a perfect cube.

Then,

=90=2.5.3.3

=2.2.2.5.5.5.3.3.3(making triplets)

=90.2.2.5.5.3=2.2.2.5.5.5.3.3.3(adding 2.2.5.5.3 in both sides)

=27000cm

so,

27000 divided by 90

=300

Therefore,300 cuboid of given measurement is required to form a cube
