Answer: 797.4 m²
Step-by-step explanation:
The surface area is just the total of the areas of each face of of a solid. In this solid, we have 2 triangles and 3 rectangles.
<h3>Triangles</h3>
We know that the two triangles of this solid are congruent, so they will have the same area. Since the area of a triangle is , two triangles would have an area of . Hence, the total area is
<h3 /><h3>Rectangles</h3>
The area of a rectangle is lw, where l is the length and w is the width. Let's find the total area of all of them.
All of the areas are a product of some number and 16. This makes sense as the length of this prism is 16. We can un-distribute this 16 to make the calculation easier.
<h3>Total</h3>
We can add both totals to get the total surface area of the solid.
The surface area of this right triangular prism is 797.4 m².
