Step-by-step explanation:

The usual formulas are useful for this.

  V = LWH

  V = (10 cm)(4 cm)(5 cm) = 200 cm³

The volume is 200 cubic centimeters.

__

  SA = 2(LW +H(L +W))

  SA = 2((10 cm)(4 cm) +(5 cm)(10 cm +4 cm)) = 2(40 +5(14)) cm² = 220 cm²

The surface area is 220 square centimeters.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
