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
\(A= 2(bh+lb+lh)\)
We substitute the value into formula
\(A= 2(5\times7+4\times5+4\times7)\)
\(A= 2(35+20+28)\)
\(A=2\times83\)
\(A= 166 m^2\)
Hence, The surface area of rectangular prism is 166 m².
