Question

Find the volume of each of the cube whose sides are. 

(i) 6.4 cm 

(ii) 1.3 m 

(iii) 1.6 m.

Answer 1

Volume of a cube(V) = a³ 

i) a = 6.4 cm 

V = (6.4)³ 

Volume of a cube (V) = a³

= 6.4 × 6.4 × 6.4 

= 262.144 cm³

ii) a = 1.3 m 

V = (1.3)³ 

= 1.3 × 1.3 × 1.3 

= 2.197 m³

iii) a = 1.6 m

V = (1.6)³ 

= 1.6 × 1.6 × 1.6 

= 4.096 m³
