Hello :)
In 8 years, the father will be 2 times older than the child.
In 8 years, the father will be 40
In 8 years, the child will be 20

Answer:
Helen’s net is correct because she reorganized the solid as a triangular prism.
This is because the net has a rectangular base and 4 triangular sides.
Step-by-step explanation:
Rectangular SA one side+1 = 30 x 9 = 270 + 1s= 270 x 2 =540sq^2
Rectangular side one side +1 = 18 x 9 = 162 +1s = 162 x 2 = 324sq^2
2 x 2 triangular sides either end = 4/3 x 15 x 27.3 + 18 x 30.9 = 409.5 (x2) = 819sq^2
=864 + 360
Pyramid area = 1236.71sq^2
Volume = V=1620^3
