Question

The volume of a cube is 528cm cubed. work out the length of its side rounded to 1DP

Answer 1

8.1

Explanation:

Formula for volume of cube. V = Volume and A = Edge.

`V=a^(3)`

`a=\sqrt[3]{v}`

Therefore we have.

`528=a^(3)`

`a=\sqrt[3]{528}`

We have to use the cube root function.

The cube root of (n) is the same as (n) raised to the 1/3 power.

n = a number

`a=v^{(1)/(3) }`

So then we have.

`528^{(1)/(3) } =a`

`a=8.08248004`

Round to 1 decimal place.

`a=8.1`
