Answer:
10. That means that 21³ (=9261) would be smaller than 10000, so would 20³ and 19³. You may notice the pattern. If you find the cube of all the integers (whole numbers) starting from 1 up to 21 you'd find all the perfect cubes.
11.) Cube
Solve for volume
V≈1.33cm³
a Edge
1.1 cm
12.) Hence, the smallest natural number by which 100 should be multiplied to make a perfect cube is 2×5=10.
