Answer:
Step-by-step explanation:
2p = 6 x 4 = 24 in
lateral surface (par) = 24 x 6 = 144 in^2
lateral surface (pyramid) = (24 x 4) / 2 = 48 in^2
lateral surface (total) = 144 + 48 = 192 in^2
The answer is.
The Lamp post is 800cm
x = height of lamp post
160/90 = x/450
450 is the length from the base of the lamp post to the end of the shadow (360+90)
cross multiple
90x = 72000
x =800cm
Have a great day!
