Answer:

The surface area of rectangular prism is 166 m².

Step-by-step explanation:

Given that,

length l= 4 m

Width b= 5 m

Height h=7 m

Using the formula of surface area of rectangular prism

[tex]A= 2(bh+lb+lh)[/tex]

We substitute the value into formula

[tex]A= 2(5\times7+4\times5+4\times7)[/tex]

[tex]A= 2(35+20+28)[/tex]

[tex]A=2\times83[/tex]

[tex]A= 166 m^2[/tex]

Hence, The surface area of rectangular prism is 166 m².
