So 45% of 35 is 16.2 so subtract 16.2 from 36 and you get A 19.2
139 is suppose to be 140 and 18 is suppose to be 20, 140 x 20 = 2800
Home this works
Answer:
Volume: 3x2x4=24 so the volume is 24 Meter3
Surface area:
52 Square meter
Answer:
0.53%
Step-by-step explanation:
hope it is well understood
I assume the volume of the larger pyramid is 108 ft^3, not 108 ft^2.
The scale factor of edges of two solids is x.
The scale factor of their areas is x^2.
The scale factor of their volumes is x^3
The areas have a scale factor of 18/8 = 2.25
The length have a scale factor of sqrt(2.25) = 1.5
The volumes have a scale factor of 3.375
108/3.375 = 32
Answer: 32 ft^3
