Question

1. Find the volume of a cube of edge (1) 5 cm, (11) 6 m,
(111) 1 m 20 cm.​

Answer 1

Answer:

1- 125 m^3 , 2- 216 m^3 , 3- 1.728 m^3

Answer 2

Given:-

• Edge of cube₁ = 5cm

• Edge of cube₂ = 6m

• Edge of cube₃ = 1m 20cm = 120cm

Solution:-

Finding volume of cube₁

Volume of cube₁

= Side × Side × Side

Putting the given values;

5cm × 5cm × 5cm

= 25cm² × 5cm

= 125cm³

Finding volume of cube₂

Volume of cube₂

= Side × Side × Side

Putting the given values;

6m × 6m × 6m

= 36m² × 6m

= 216m³

Finding volume of cube₃

Volume of cube₃

= Side × Side × Side

Putting the given values;

120cm × 120cm × 120cm

= 14400cm² × 120cm

= 1728000cm³

= 1.728 m³

Answer:-

▪︎Volume of cube₁ = 125cm³

▪︎Volume of cube₂ = 216m³

▪︎Volume of cube₃ = 1.728 m³
