I need help with math the question is

velikii [3]

Answer:

$P=2(S-lw)/h$

Step-by-step explanation:

we have that

The formula for the surface area of the enclosed space is

$S=lw+0.5Ph$

Solve for P

That means ------> isolate the variable P

Subtract lw both sides

$S-lw=lw+0.5Ph-lw$

$S-lw=0.5Ph$

Multiply by 2 both sides

$2(S-lw)=(2)0.5Ph$

$2(S-lw)=Ph$

Divide by h both sides

$2(S-lw)/h=Ph/h$

$2(S-lw)/h=P$

Rewrite

$P=2(S-lw)/h$
