Answer 2

The surface area of a right prism can be calculated using
the following formula: SA 5 2B 1 hP, where B is the area of
the base, h is the height of the prism, and P is the perimeter
of the base.
The lateral area of a figure is the area of the non-base faces
only. When a prism has its bases facing up and down, the
lateral area is the area of the vertical faces. (For a rectangular
prism, any pair of opposite faces can be bases.) The lateral
area of a right prism can be calculated by multiplying the
perimeter of the base by the height of the prism. This is
summarized by the formula: LA 5 hP.
