Find the volume of a cube whose side is
(i) 4 cm
(ii) 8 cm
(iii) 1.5 dm
(iv) 1.2 m
(v) 25 mm
(i) Given,
side of cube = 4 cm
volume of cube = (side)3 = 43 = 64 cm3
(ii) side of cube = 8 cm
volume of cube =(side)3 = 83 = 512 cm3
(iii) side of cube = 1.5 dm
volume of cube = (side)3 = 1.53 = 3.375 dm3 = 3375 cm3
(iv) side of cube = 1.2 m
volume of cube = 1.23 = 1.728 m3
(v) side of cube = 25 mm
volume of cube = 253 = 15625 mm3= 15.625 cm3
