Answer:
150.88 cm²
Step-by-step explanation:
From the figure above;
From the figure you realize, there are three pairs of similar rectangles;
Thus; since area of a rectangle is L × W
Then;
First pair;
Area = 7.4 cm × 3.1 cm × 2
= 45.88 cm²
Second pair;
Area = 5 cm × 3.1 cm × 2
= 31 cm²
Third pair;
Area = 5 cm × 7.4 cm × 2
= 74 cm²
Therefore;
The total surface area = 45.88 cm² + 31 cm² + 74 cm²
= 150.88 cm²
Thus, the total surface area of the rectangular prism is 150.88 cm²
