Lower Bound, Upper Bound, Volume, Surface Area, iGCSE Math GCSE Math, 10th Grade Algebra

Lower Bound and Upper Bound. This is from a past exam question for higher Tier iGCSE/GCSE. As well as laying out the strategy for finding lower and upper bound for quantities rounded to 2 decimal places, I have also shown the properties of cubes and hence been able to find the cube root of numbers.
Is there a topic or maths question you'd like me to help solve?
