Question

if a cube that has a length height and width of 4cm is broken down into 8 cubes of equal size what is the surface area of the 8cm cubes ​

Answer 1

144 cm²

Step-by-step explanation:

In dividing to 8 cubes the side of a cube will be 2 cm.

It can be taken by volume as

4×4×4 = 8×(l×l×l) where l = length of the cube required.

So surface area of a small cube is 6×(2×2) = 24 cm²

Six such cubes will have a surface area of 144 cm²
