Step-by-step explanation:
Side of the base of the pyramid: s=54 m
Height of the pyramid: h=260 m
Volumen of the building = Volumen of the pyramid = V=?
V=Ab*h/3
Area of the base = Area of a square = Ab=s^2=(54 m)^2→Ab=2,916 m^2
V=(2,916 m^2)*(260 m)/3→V=252,720 <span>m³
Answer: T</span>he volume of the building is 252,720 m³
Answer:
132cm
Step-by-step explanation:
Split there firgue into shapes you know
there is a rectangle and a Trapezoid
A = bh
A = 7×4
A = 28cm
Trapezoid
A = 1/2h(b+b)
A = 1/2×8(19+7)
A = 1/2×8(26)
A = 1/2(208)
A = 104cm
Add them together
104 + 28 = 132
