Yes scale factor means ratio. The height of the smaller pyramid to the larger pyramid in ratio form is 8:24 which simplifies to 1:3. The ratio of its areas is the scale factor squared, so 1^2:3^2=1:9. Since the surface area of the smaller pyramid is 124, the surface area of the larger pyramid must be 124x9. The ratio of volumes is the scale factor cubed, so 1^3:3^3=1:27. If the volume of the larger pyramid is 648, then the volume of the smaller pyramid is 1/27 of that, which equals 24.

Step-by-step explanation:
Answer:
technically only 10 but if you round up then its 11.
Step-by-step explanation:
97 divided by 15 ~6.47
71 divided by 6.47~ 10.97
50= 4x + x
50=5x
50÷5=x
x=10
