#### Question

A 4 cm cube is cut into 1 cm cubes. Calculate the total surface area of all the small cubes.

#### Solution

Edge of cube = 4cm

Volume of 4cm cube = `(4cm)^3= 64cm^2`

Edge of cube =`1cm`

Volume of 1cm cube =`(1cm)^3`

∴Total number of small cubes = `(64cm^3)/(1cm^3)=64`

∴ Total surface area of 64cm all cubes

`=64xx6xx(1cm)^2`

`=384cm^2`

Is there an error in this question or solution?
