Answer:
The surface area is 177 square inches
Step-by-step explanation:
Given
[tex]Length = 10[/tex]
[tex]Width = 3[/tex]
[tex]Height = 4\frac{1}{2}[/tex]
Required
The surface area
This is calculated as:
[tex]Area = 2 * (Length * Width + Length * Height + Width * Height)[/tex]
So, we have:
[tex]Area = 2 * (10* 3+ 10* 4\frac{1}{2}+ 3* 4\frac{1}{2})[/tex]
[tex]Area = 2 * (30+ 45+ 13\frac{1}{2})[/tex]
[tex]Area = 2 * (88\frac{1}{2})[/tex]
[tex]Area = 177[/tex]
