Answer:
Surface area of prism = 286 ft².
Step-by-step 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 =
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.
