Question

A cube has a volume of 60cm^3 estimate the length of one edge

Answer 1

3.91cm

Explanation:

when we calculate the area of a cube is

`x^(3)`

because the Volume (V)=Area*Height

and the Area (A) =
`x^(2)`

and the Height =
`x`

so

`V=x^(2) *x\\\\V=x^(3)`

and we know that

V=60

`60=x^3\\x=\sqrt[3]{60} \\\\x=3.9148676411688635954249360604116714249316822143474229176559381605....\\\\`

so we can say that

x=3.91cm

Answer 2

3.9 cm =s

Explanation:

The volume of a cube is

V = s^3 where s is the side length

60 = s^3

Take the cube root of each side

60 ^ 1/3 = s^3 ^ 1/3

3.914867641 = s

3.9 cm =s
