a rectangular prism has a base that is 6 M by 3.5 m in the prism is 9 meters high what is the surface area of the prism

213 meters squared

Step-by-step explanation:

The surface area of a rectangular prism is found using the formula A=2 (wl+hl+hw). Here substitute l = 6, w = 3.5 and h = 9.

A = 2 ((3.5*6) + (9*6) + (3.5*9))

A = 2 (21 + 54 + 31.5)

A = 2 (106.5)

A = 213
