Question

Evaluate:
(i) (1.2)3
(ii) (3.5)³
(iii) (0.8)³
(iv) (0.05)³

Answer 1

(i) (1.2)³ = $\left(1.2\times 1.2\times 1.2\right)$= 1.728
Thus, the cube of 1.2 is 1.728.
(ii) (3.5)³= $\left(3.5\times 3.5\times 3.5\right)$= 42.875
Thus, the cube of 3.5 is 42.875.
(iii) (0.8)³= $\left(0.8\times 0.8\times 0.8\right)$= 0.512
Thus, the cube of 0.8 is 0.512.
(iv) (0.05)³= $\left(0.05\times 0.05\times 0.05\right)$= 0.000125
Thus, the cube of 0.05 is 0.000125.
