Question

8. Sunil 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:

20 cuboids

Step-by-step explanation:

Cube is a special form of cuboid in which length, breadth and height are equal i.e., all the dimensions of a cube are equal in measure. Therefore, 20 cuboids each of sides 5 cm, 2 cm, 5 cm will be needed to form a cube.

Answer 2

Answer:

cuboid dimensions = (5,2,5)

volume = 50cm3

cube side length = LCM of (5,2,5)

= 10cm

volume = 10 cube = 1000 cm3

number of cuboid required = 1000/50 = 20
