Answer:
The surface area is 86.9
Step-by-step explanation:
First find the area of the base:
5.3 • 2 = 10.6
The area opposite of the base are equal:
10.6 + 10.6 = 21.2
Find the area of the front rectangle:
5.3 • 4.5 = 23.85
The area opposite of the rectangle are equal:
23.85 + 23.85 = 47.7
Find the area of the rectangle on the sides:
4.5 • 2 = 9
The area opposite of the shape on the side are equal:
9 + 9 = 18
Add up the areas:
21.2 + 47.7 + 18 = 86.9
