The surface area is 88.
To determine the surface area of a rectangular prism, the two sides, adjacent sides, and ends of the prism must be added up. To do this, the sides are the product of the prism's length and height, the adjacent sides the width and height, and the ends the product of the length and width.
The surface area of a cylinder prism has round shape and the surface of a rectangular prism has a square shape.
surface area of a rectangular prism is the formula: 2lw+2wh+2lh
164 square units.
To find the surface area of an equilateral triangular prism you take the area of the rectangular sides and the triangular bases and add them up and your done.
u have to find the surface area for individual sides. so lxw for each individual side
It depends on how many sides are part of the "opening".
For each side of a rectangular prism there is an opposite side that is identical in measurement. So there are two width sides, two length sides, and two height sides.
With a rectangular prism with these dimensions, you'd have 2 sides with an area of 15*5, two sides with an area of 5*4 and two sides with an area of 4*15. The surface area is 15*5+15*5+5*4+5*4+4*15+4*15 = 310.

Squared. When you find surface area, you are only finding the area of the shapes that make up the three-denominational shape.
