A square pyramid is shown sitting on its base.

please reply with

The surface area of the pyramid is _
square centimeters.

A = 384 cm²

Step-by-step explanation:

h = 8 cm

s = 10 cm

a = 12 cm

e = 11.6619 cm

r = 6 cm

V = 384 cm3³

L = 240 cm²

B = 144 cm²

A = 384 cm²

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

Formula: A = a(a + √(a² + 4h²))

Surface area of the pyramid =
