Question

A cube having each side of unit length is cut into two parts by plane through the diagonal of two opposite faces what is the total surface area of each of these parts​

Answer 1

Ans= 2√3+6 unit^2

TSA of cube=6×side^2

cube cutted diagonally so we get two extra face which is made by the diagonals

TSA of cube = 6×(1)^2= 6 unit^2

Area made by diagonals= √3× 1

Required area= (6+ 2√3 ) unit^2
