Answer:
height h = 324 cm
slant height s = 324.61669704438 cm
side length a = 40 cm
lateral edge length e = 325.23222472566 cm
1/2 side length r = 20 cm
volume V = 172800 cm^3
lateral surface area L = 25969.33576355 cm^2
base surface area B = 1600 cm^2
total surface area A = 27569.33576355 cm^2
Explanation:
Total Surface Area of a square pyramid:
A = L + B = a^2 + a√(a^2 + 4h^2))
A = a(a + √(a^2 + 4h^2))
Agenda:
h = height
s = slant height
a = side length
e = lateral edge length
r = a/2
V = volume
L = lateral surface area
B = base surface area
A = total surface area
