Answer:
z is an unknown number it sometimes stands for 149
Step-by-step explanation:
Volume of Original Prism = base area * Height = 3 * 4 = 12
After dilation factor = 12 * 3/2 = 6 * 3 = 18
In short, Your Answer would be 18 m³
Hope this helps!
The average rate of change is 0.19
A(base)=6*6=36
A( triangle)=1/2*(base of the triangle)*height( of the triangle)=1/2*6*4=12
one base +4 triangles=36+4*12=36+48 =84 cm²
