Question

A 4cm cube is cut into 1cm cubes. Calculate the total surface area of the small cubes. What is the ratio of surface area of small cubes to that of large cube?

Answer 1

Answer:

TSA of larger cube =6×side2

=6×4²

.. =6×16

=96cm²

TSA of smaller cube =6×1²

=6cm²

Now,TSA of smaller cube/TSA of larger cube

= 6/96

=1/16

=1:16
