Answer:
A) 3; B) 1116 m²; C) 24 m³; D) 1/27
Step-by-step explanation:
A) Scale factor
The scale factor is the ratio of the heights of the two pyramids.
h₂/h₁ = 24/8 = 3
B) Surface area
The ratio of the surface areas is the square of the scale factor.
A₂/A₁ = 3²
A₂/124 = 9
A₂ = 124 × 9 = 1116 m²
The volume of the larger pyramid is 1116 m².
C) Volume
The ratio of the volumes is the cube of the scale factor.
V₂/V₁ = 3³
648/V₁ = 27
648 = 27V₁
V₁ = 648/27 = 24 m³
The volume of the smaller pyramid is 24 m³.
D) Volume ratio
V₁/V₂ = 24/648 = 1/27
The volume ratio is 1/27.

Answer:
4, tell me if wrong
Step-by-step explanation:
c² = b² + a²
now, 5x5 = 25
3 x 3 = 9
25 - 9 =

Answer:
x = 67.5 ft.
Step-by-step explanation:
The triangles MBA and MPN are similar.
So corresponding sides are in the same ratio.
Therefore x / 97.5 = (71.5 - 22) / 71.5
x / 97.5 = 49.5 / 71.5
x = 49.5 * 97.5 / 71.5
x = 67.5 ft,
