Surface area is the area of a base so:
We have to mulityply the height by the length to find the answer so the answer would be 4x6 which is 24square cm hope this helps!
We want to find the axis of symmetry of the function;

STEP 1:
The equation for the axis of symmetry of a line is given as;

From the equation, a = 6 and b = -3, so,
STEP 2: Insert the values of a and b into the equation to obtain;

CONCLUSION:
Therefore, we see that the axis of symmetry is the line;
60000 is the answer for your problem
