A surface S=10hatj is kept in an electric field of vecE=3hati+5hatj+6hatk . How much electric flux will come out through the surface?

In vacuum (i) find out the electric flux across an area vec S = 10 hatj placed in an electric field vec E = 2 hati + 4 hatj + 7 hatk , (ii) How many electric charges are to be placed at a point such that 4400 number of electric lines of forces with emerge from that point ? (iii) What will be the electric flux through any one of the faces of a cube of side 10 cm if a charge of 1 esu is placed at the centre of the cube ?

The electric flux coming out of the equi-potential surface is -
