1. cube root of 140 × 2450=cube root of 343000=70
2. cube root of 1000 + cube root of 0.008 + cube root of 0.125 is 10+0.2+0.5=10.7
3. surface area formula of a cube is 6a square means square root of 150 by 6 is 5 the side of a cube is 5
4. 243000÷9=27000 ,27000 is a perfect cube of 30,so we should divided by 9 to get the perfect cube
5. the cube root of 216 is 6, so we should need a side of 6 square metres
6. the three numbers is 14, 21, 28 . if we take cube of 14 and 21 and 28 then add it we get 33957
7. 126×140×525=9261000, the volume of a cuboid is same of volume of a cube , the cube root of 9261000 is 210
8. a number is doubled means multiplied by 2, if we take example 5 then it is doubled means multiplied by 2 so 5 x 2 we should take the cube of it then 125 x 8 it means that when we doubles
