Question

question 10 (5 points) listen kaylee found the surface area, in square inches of a rectangular prism by using this formula. 2(5 × 3) + 2(5 × 8) + 2(3 × 8) what is the surface area of the prism, in square inches? 85 158 238 40

Explanation:

Step1: Calculate each product inside the parentheses

First, calculate \(5\times3 = 15\), \(5\times8 = 40\), and \(3\times8 = 24\).
So the expression becomes \(2(15)+2(40)+2(24)\).

Step2: Multiply each term by 2

Next, multiply each product by 2: \(2\times15 = 30\), \(2\times40 = 80\), and \(2\times24 = 48\).
Now the expression is \(30 + 80 + 48\).

Step3: Add the results together

Finally, add the three numbers: \(30+80 = 110\), and \(110 + 48 = 158\).

Answer:

158
