Question

which expression represents the total surface area of the prism shown?
2(5·7)+2(5·10)+2(7·10)
find the surface area of the prism.
s.a. = □ in.²

Explanation:

Step1: Calculate each term

First, calculate \(2(5 \cdot 7)\): \(5 \cdot 7 = 35\), so \(2 \times 35 = 70\).
Then, calculate \(2(5 \cdot 10)\): \(5 \cdot 10 = 50\), so \(2 \times 50 = 100\).
Next, calculate \(2(7 \cdot 10)\): \(7 \cdot 10 = 70\), so \(2 \times 70 = 140\).

Step2: Sum the terms

Now, add the three results together: \(70 + 100 + 140 = 310\).

Answer:

310
