The surface area of the box is being referred to as A
The surface area will be the sum of the four rectangular sides' areas and the base area.
Base area = x²
Rectangular side area = xh
A = x² + 4xh
Volume is, as you said,
V = x²h
Lets substitute h from the formula of A to obtain A in our final answer. Substituting x is possible, but more difficult
(A - x²)/4x = h
V = (x²) * (A - x²)/4x
V = (Ax - x³)/4
I think it’s 36, Are there options??
87/6-66/6
=21/6
=3 3/6
=3 1/2
=3.5

8z + 3z = 8
Combine like terms: 8z + 3z = 11z
11z = 8
Solving
11z = 8
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Divide each side by '11'.
z = 0.7272727273
Simplifying
z = 0.7272727273</span>
