Answer:
162.1
Step-by-step explanation:
The surface area is just the areas of each of the sides of this prism. As the base of this triangular pyramid is an equilateral triangle, we know that the three lateral triangles are all congruent.
The area of an equilateral triangle is given by:
, where s is the side length. Here, our base is an equilateral triangle with side length s = 8. Plug this in:

≈ 27.7
The area of a regular triangle is:
, where b is the base and h is the height. Here, b = 8 and h = 11.2. Plug this in:


Since there are three of this kind of triangle, we need to multiply 44.8 by 3:
44.8 * 3 = 134.4
Add this to the value above:
134.4 + 27.7 = 162.1
Hope this helps!
Hello!
The ratio of 1:5
The ratio we are find is 3 : x
We have to find what happened between the ratios
To do this you divide the new number by the old one
3 / 1 = 3
They multiplied the scale by 3 to get the actual wall
Use this to get the length of the wall
3 * 5 = 15
The answer is 15 inches or 1ft 3in
Hope this helps!
