Answer:
528000 ft²
Step-by-step explanation:
The Pyramid Arena has a shape of a square pyramid. A square pyramid is a pyramid with a square base and the top point is directly above the center of the base. It consist of 5 faces (base and 4 triangles), 8 edges and 5 vertices.
Given:
length of base (b) = 600 ft and height of lateral face (h) = 440 ft.
Since the lateral faces are made of glass, the area of each lateral face is the same as the area of a triangle with base same as base length and height same as height of lateral face.
Therefore, area of each lateral face = 1/2 × b × h = 1/2 × 440 × 600 = 132000 ft²
The lateral faces are made almost completely of glass and they are 4 lateral faces, therefore the total area of the glass in the Pyramid Arena = 4 × 132000 ft² = 528000 ft²

Answer:
1/5 and 3/15
Step-by-step explanation:
12/60 reduces to 1/5 if we divide numerator and denominator by 12.
Thus, 12/60 = 1/5.
If we now multiply both numerator and denominator by 3, we get 3/15, which is identical to 1/5.
Thus, the two fractions in question are 1/5 and 3/15.
