Answer:
The surface area is 46 square inches
Step-by-step explanation:
The question is roughly formatted.
From the complete question, we have the following parameters.\
Plan A:
Shape: Rectangular Prism
[tex]Height = 3in[/tex]
[tex]Length = 1\ in[/tex]
[tex]Width = 5in[/tex]
Plan B:
Shape: Triangular Prism
[tex]Base: 2.8\ in\ by\ 2\ in[/tex]
[tex]Height = 2\ in[/tex]
[tex]Slant\ height =5[/tex]
Required
Determine the total surface area of A
Plan A is a rectangular prism
The surface area is calculated as:
[tex]Area = 2 *[Length * Width + Height * Width + Length * Height][/tex]
So, we have:
[tex]Area = 2 *[1in * 5in + 3in * 5in+ 1in* 3in][/tex]
[tex]Area = 2 *[5in^2 + 15in^2+ 3in^2][/tex]
[tex]Area = 2 *[23in^2][/tex]
[tex]Area = 46in^2[/tex]
