Step-by-step explanation:
Since the triangles are right angled and are similar,
by Pythagoras theorem,
(10√3)^2 = (5√3)^2 + a^2
a = 15, a > 0

Answer:
363.6
Step-by-step explanation:
Given in the question,
side of square = 10
Step 1
To find the slant height pyramid we will use pythagorus theorem
13² = 5² + height²
height = √13² - 5²
= 12
Now find the height of the pyramid
12² = 5² + height²
height = 10.91
Step 2
Base area of the pyramid
area = l²
= 10²
= 100
Step 3
Volume = 1/3(height)(basearea)
= 1/3(10.91)(100)
= 363.6
