Respuesta :
Surface area of rectangular prism is [tex]Area = 8,490cm^2[/tex] . Correct option A. 8,490 square centimeters .
Step-by-step explanation:
Here we have , The figure below is a net for a rectangular prism. Side a = 75 centimeters, side b = 19 centimeters, and side c = 30 centimeters. We need to find What is the surface area of this figure . Let's find out:
We know that Surface area of rectangular prism = [tex]2(lb+bw+wl)[/tex] . According to Question we have following parameters:
[tex]l =75cm\\b=19cm\\w=30cm\\Area= 2(lb+bw+wl) =?[/tex]
So , Surface area of rectangular prism
⇒ [tex]Area = 2(lb+bw+wl)[/tex]
⇒ [tex]Area = 2((75)19+(19)30+(30)75)[/tex]
⇒ [tex]Area = 2(1425+570+2250)[/tex]
⇒ [tex]Area = 8,490cm^2[/tex]
Therefore , Surface area of rectangular prism is [tex]Area = 8,490cm^2[/tex] . Correct option A. 8,490 square centimeters .
