Given the equation:
SA = 2B + Ph
The given equation represents the surface area of a triangular prism.
Let's determine the meaning of B.
Since the formula represents the surface area of a triangular prism, we have the following:
B is the area of the triangular base
P is the perimeter of the base
h is the height of the prism.
Therefore the statement which describes the meaning of B is:
B is the area of the base.
ANSWER:
B is the area of the base.
