A pentagonal prism has a base area of 124 square inches. The lateral area (area of sides) is made up of 5 equal-sized rectangles that are each 80 square inches. What is the surface area of the pentagonal prism?

The surface area of the pentagonal prism is equal to 648 square inches

Step-by-step explanation:

we know that

The surface area of the pentagonal prism is equal to the area of the base and the top plus the lateral area

so

where

B is the area of the pentagonal base

LA is the lateral area (area of 5 equal-sized rectangles)

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
