Question

A spherical shell with inner radius 20 units and outer
radius 30 units is molten and reformed into 100
identical cubes. What will be the side length of each
cube?​

Answer 1

Step-by-step explanation:

vol of sphere = 3.14. × (900-400)

3.14 × 500 = 314 ×5 = 1570

now acc to question =

volume of sphere =100× cubes

1570 =100 ×l^3

1570÷100 =l^3

15.7 =l^3

l =

Answer 2

Answer:

The length of eacg side of cube is approx 2.60 units
