Question

Arjun makes a cuboid of plasticine of sides 5 cm, 4 cm ,2 cm. How many such cuboids will be needed to form a cube

Answer 1

Answer:

25.

Step-by-step explanation:

Volume of the cuboid = 5x4x2 = 40cm²

Nearest cube for 40 ending with zero = 1000.

(40 ends with zero. So, the volume of cube formed from this cuboid will be ending with zero. And nearest cube ending with zero is 1000).

Assume  that 'x' cuboids are required to make a cube.

40 × x = 1000

x = 1000/40

x = 25

Answer 2

Answer:

25

Step-by-step explanation:

Volume of the cuboid = 5x4x2 = 40cm²

Nearest cube for 40 ending with zero = 1000.

let x be the cuboids required to make a cube.

40 × x = 1000

x = 1000/40

x = 25
