Question

Rahul makes a cuboid of plasticine of side 7 CM ;3 CM 7 CM How much cuboid will be needed to form a cube

Answer 1

Answer:

Volume of cuboid=7*3*7=147

Let the side of the cube be x

Therefore, 3x=147

Therefore, x=49cm

Therefore, the volume of cuboid required to make a cube of 49cm is 147cm^3

Answer 2

Step-by-step explanation:

Volume of a cuboid =L×B×H

=7×3×7=147cm³

Volume of a cube =side ³

so to form a cube we need to make 147 as a perfect cube by multiplying some number

first take prime factor to 147

147 =3×7×7

so we should multiply by 3×3×7 to get a perfect cube.

therefore we need 147 cuboid to make a cube
