A rectangular prism has a base that is 6 meters by 3.5 meters, and the prism is 9 meters high. What is the surface area of the prism?

213 m^2

Step-by-step explanation:

The surface area for a rectangle prism is given by

A=2 (wl+hl+hw)

We know the base is 6 meters by 3.5 m so l = 6 and width = 3.5

The heigth is 9 m

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

= 2 * (21 + 54 + 31.5)

= 2 * (106.5)

=213 m^2
