14         10

------ = ------

21          x

Using cross products

14x = 21*10

14x =210

Divide each side by 14

14x/14 = 210/14

x =15

A square pyramid is shown. What is the surface area?
ICE Princess25 [194]

Answer:The answer is B


Step-by-step explanation:

first find te height:

1.5/2=0.75 (this will be your "b" of the pythagorean theorem for finding the height)

now do the  pythagorean theorem:

a^2+0.75^2=3^2

(height)= 2.905

A= a^2+2a√((a^2/4)+h^2)

a (base edge)= 1.5

h (height)= 2.905

Calculate and you get B as your answer.
