Question

Which model shows:
`\sqrt[3]{64} = 4`

Answer 1

The expression is

`\sqrt[3]{64}=4`

Considering that the images are cubes, the value 64 corresponds to the volume of said cubes.

The volume of a cube is calculated as height*width*length. Let a represent the length of its sides, the volume of a cube is:

V= a³

64= a³

∛64= a

a= 4

The cube that represents the expression is the one with sides of 4 units of length.

Asuming each square in the figures represents a unit, the correct choise is the 3rth one, or first one of the second row.
