Question

How many cuboids of dimensions 3cm, 4cm, 8cm will be needed to form a cube?

Answer 1

Answer:

18

Step-by-step explanation:

Firstly , all the cuboids used for making the cube will have the same volume as that of the cube.

So,

n x 4x3x8 = x^3

where n = no. of cuboids needed to form cube

x = cube

therefore,

n x 96 = x^3

96 = 2×2×2×2×2×3

2×3×3 = 18 must be multiplied to 96 to form a perfect cube.

Therefore,

n = 18

Hence, we need 18 cuboids of those dimensions to make a cube.

Answer 2

Answer:

this is your ans -18......

Step-by-step explanation:

• Firstly , all the cuboids used for making the cube will have the same volume as that of the cube.
• So,
• n x 4x3x8 = x^3
• where n = no. of cuboids needed to form cube
• x = cube.............
• therefore,
• n x 96 = x^3
• $x ^3 = 96 n$
• 96 = 2×2×2×2×2×3
• 2×3×3 = 18 must be multiplied to 96 to form a perfect cube.
• Therefore,
• n = 18
• Hence, we need 18 cuboids of those dimensions to make a cube.
