Question

How many cubes of 5 cm are equivalent in volume to a 15 cm cube​

Answer 1

Answer:

the number of cube is 27

Step-by-step explanation:

Given that,

Side of smaller cube = 5 cm

Side of bigger cube = 15 cm

We need to calculate the number of cube

Using formula of volume of cube

Volume of cube = side x side x side

\text{Number of cube}=\dfrac{V_{big}}{V_{sm}}Number of cube=

V

sm

V

big

Put the value into the formula

\text{Number of cube}=\dfrac{15\times15\times15}{5\times5\times5}Number of cube=

5×5×5

15×15×15

]\text{Number of cube}=27]Number of cube=27

Hence, The number of cube is 27.

Answer 2

Answer:

V of cube 5 × 5 × 5=125

V of cube 15 × 15 × 15=3375

3375÷125=27
