What is the unit vector n on the bottom face of the box?
n =  

What is the electric flux on the bottom face of the box?
bottom =  V·m

What is the electric flux on the top face of the box?
top =  V·m

What is the electric flux on the left face of the box?
left =  V·m

What is the electric flux on the right face of the box?
right =  V·m

What is the electric flux on the front face of the box?
front =  V·m

What is the electric flux on the back face of the box?
back =  V·m

How much charge is inside the box (amount and sign)?
Qinside =  C

Explanation / Answer

Here,

E1 = < 60, 48, 0 > N/C

E2 = < 135, 108, 0 > N/C

for the bottom of the face of the box

unit vector n of the bottom face = 0.09 * 0.02 * m^2 (-j)

unit vector n of the bottom face = -1.8 * 10^-3 j m^2

unit vector n of the bottom face = < 0 , -1.8 * 10^-3 , 0 > m^2

-------------------

electruc flux on the bottom face = E1 * Area

electruc flux on the bottom face = < 60, 48, 0 > . < 0 , -1.8 * 10^-3 , 0 >

electruc flux on the bottom face = - 1.8 *10^-3 * 48 N.m^2/C

electruc flux on the bottom face = 0.0865 N.m^2/C

-----------------------------------

for the eletric flux through the top face = E2 * Area

the eletric flux through the top face = < 135, 108, 0 > . < 0 , 1.8 * 10^-3 , 0 >

the eletric flux through the top face = 108 * 1.8 *10^-3 N.m^2/C

the eletric flux through the top face = 0.195 N.m^2/C

the the eletric flux through the top face is 0.195 N.m^2/C

----------------------------------------------

for the electric flux through the left face = E2 * Area

the electric flux through the left face = < 135, 108, 0 > . < 0.02 * 0.09 , 0 , 0 >

the electric flux through the left face = 135 * 0.02 * 0.09 N.m^2/C

the electric flux through the left face = 0.243 N.m^2/C

the electric flux through the left face is 0.243 N.m^2/C
