Question

If a³= 216 cm³ then a= 6cm​

Answer 1

Answer:

Vol. of larger metal cube = vol. of three smaller cubes

=(3)³ + 4³ + 5³

= 27 + 64 + 125

= 216 cm³

vol.of larger metal cube = 216 cm³

(a)³ = 216 cm³

a³ = 6³

a = 6 cm

therefore edge of larger metal cube is 6 cm

Answer 2

Answer:

Correct

Step-by-step explanation:

Because

a³ = 216 cm³

so

³√a³ = ³√216 cm³

=> a = ³√216 ³√cm³

=> a = ³√6³ (cm)

=> a = 6 cm
