Calculate 19543

Calculate the surface of a prism with a square base whose mantle is a rectangle with sides of 18cm and 8cm. How many solutions does the task have? List all solutions.

Correct answer:

S1 =  184.5 cm2
S2 =  152 cm2

Step-by-step explanation:

x=18 cm c=8 cm x=o=4a a=x/4=18/4=29=4.5 cm  S1=2 a2+x c=2 4.52+18 8=184.5 cm2
x=8 cm c=18 cm a=x/4=8/4=2 cm  S2=2 a2+x c=2 22+8 18=152 cm2
