Answer:
a) Using the formula of similarity, we have:
(L1/L2)^2=A1/A2
(4/8)^2= 80/x
16/64= 80/x
x= 64*80/16
x= 320
Ans: Surface area of shape B= 320 square centimeters.
b) Using the formula of similarity, we have:
(L1/L2)^3=V1/V2
(4/8)^3=x/600
x= 64*600/512
x=75
Ans: Volume of shape B is 75 Cubic centimeters.
