Question

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

Answer 1

(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 = 1.2 3 = 1.728 m³

(v) side of cube = 25 mm

volume of cube = 25³ = 15625 mm³ = 15.625 cm³
