Find the surface area of the right square pyramid. Round your answer to the nearest hundredth.
A.
117.66
B.
123.21
C.
145.75
D.
182.04

Answer 1

start by finding the area of the base

Answer 2

i have the area of the rectangular prism

Answer 3

\[A=a^{2}+2a \sqrt{\frac{ a^{2} }{ 4 }}+h^{2}\]

Use this formula
A=Base edge
H=Height

Answer 4

The pyramid is a right square pyramid.

That means the base is a square. We are shown that all edges of the base measure 5.3 yd.
That means you can find the area of the base using the formula for the area of a square.

Now you need to find the areas of the 4 triangular sides.
All sides are congruent, so you need to find the area of one triangular side, and multiply that area by 4. Each side is a triangle with base 5.3 yd and height 11.1 yd. Use the formula for the area of a triangle with those measures for the base and height, and find the area of one side.

Then multiply the area of one side by 4 and add to the area of the square base.
