Answer 2

Surface area of prism = 286 ft².

Explanation:

Given : A prism with measurements of 5ft, 9ft, & the height of 7ft..

To find : What is the surface area of the prism .

Solution : We have given that a prism with

Length =5 ft,

Width = 9 ft .

Height = 7 ft.

Surface area of prism =
`2(length* width\ +\ height*width\ +\ height*length})`

Plugging the values

Surface area of prism = 2 ( 5* 9 + 9 * 7 + 7 * 5)

Surface area of prism = 2 (45+ 63 + 35)

Surface area of prism = 2 ( 143).

Surface area of prism = 286 ft².

Therefore, Surface area of prism = 286 ft².
