Lazarus · Answer 1

125 m²

Step-by-step explanation:

SA = square base + 4 slant triangles

Area of square = 5² = 25 m²

Area of a slant triangle = ½ (5) (10) = 25 m²

SA = 25 + 4 (25) = 125 m²

Alina Hodge · Answer 2

h = 10 m

s = 10.3078 m

a = 5 m

e = 10.6066 m

r = 2.5 m

V = 83.3333 m^3

L = 103.078 m^2

B = 25 m^2

A = 128.078 m^2
