To find the surface area of a three dimensional figure, you must find the area of each of its faces and then multiply the areas. true or false

False

Step-by-step explanation:

we know that

To find the surface area of a three dimensional figure, you must find the area of each of its faces and then sum the areas

The surface area of a three dimensional figure is equal to the area of its bases plus the area of its lateral faces

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
