A rectangular prism has a base that is 6 m by 3.5 m in the prism is 9 m high what is the surface area of the prism
brilliants [131]

Answer:

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
