CBSE Class 8 Maths Cube Numbers
- cube root of 64000
- find the cube of 0.3
-
Evaluate
- Solve: (-425)-(-125)-(-53)+90
- Observe the following pattern of sums of odd numbers: 1 = 1 = 13 3 + 5 = 8 = 23 7 + 9 + 11 = 27 = 33 13 + 15 + 17 + 19 = 64 = 43 21 + 23 + 25 + 27 + 29 = 125 = 53 Express the following numbers in the same pattern i) 73 ii) 83 iii) 93
- If 23-13 = 1 + 2 x 1 x 3 33-22 = 1 + 3 x 2 x 3 Find : i) 73 - 63 ii) 123 - 113
- Find the cube roots of 64 and 216 by cube pattern: 13 = 1 23-13 = 7 33-23 = 19 43-33 = 37 53-43 = 61 63-53 = 91 ......
