Hello readers,

Today I am compiling some questions on Area – combining moderate and difficult level – such questions are very common for IBPS Clerical and upcoming NIA exam too.

Time yourselves and all the best!

A cube whose edge is 20cm long has a circle on each of its faces painted black. What is the total area of the unpainted surface of the cube if the circles are of the largest area possible?

Ans- 514.28cm square
