Find the volume in `c u\ d m` of each of the cubes whose side is (i) `1. 2 m` (ii) `25 c m` (iii) `1\ d m\ \ 5c m`

Text Solution

Verified by Experts

(i) Side of cube(a)= '1.5' m
= '1.5 x 1.5 x 1.5m³ = 3.375m³'
='3.375 x 1000 = 3375dm³' Volume = a³ = '(7.5)³dm³'
= '421.875dm³'
(iii) Side of cube (a) = 2 dm 5 cm = '2.5 dm'
Volume = (a)³ = '(2.5)³dm³'
= '15.625dm³'
