Question

find the edge of the cube whose volume is 729 cm*3​

Answer 1

Answer:

729÷ 3 is the answer alright

Answer 2

Answer:

9 cm

Step-by-step explanation:

We know that

cube's volume = edge³

So

edge³ = cube's volume

a³ = cube's volume

$= > {a}^{3} = 729 {cm}^{3} \\ = > \sqrt[3]{ {a}^{3} } = \sqrt[3]{ {729cm}^{3} } \\ = > a = \sqrt[3]{729} \: cm \\ = > a = \sqrt[3]{9 \times 9 \times 9} \: cm \\ = > a = \sqrt[3]{ {9}^{3} } \: cm \\ = > a = 9cm$

a = arm (edge, side) of cube

hope it helps.
