Question

find the diagonal of a cube of Edge 8 cm​

Answer 1

Answer:

hah, we know that every side of cube consists of a square and every angle of square is 90 so if we use pythagorus theorum we get the diagonal i.e

root under 8^2 +8^2

= root under 64+ 64

= root under 128

=8root2 thus our diagonal is 8root2

( sorry i am writing root instead of its symbol coz i donno how to add symbol)
