1. Find the surface area of the following figure.

Answer:
190 in²
Here given :
surface area of a rectangular prism:
2 ( Length * Width + Length * Height + Height * Width )
2 ( 10 * 5 + 10 * 3 + 3 * 5 )
2 ( 50 + 30 + 15 )
2 (95)
190 in²
Answer:
Step-by-step explanation:
Area of rectangle = length x width
Surface Area = sum of area of all surfaces
= sum of area of the 6 rectangles
= 5x10 + 5x10 + 5x3 + 5x3 + 3x10 + 3x10
= 190 square inches
