Answer:
<u>The correct answer is B. 145 in²</u>
Step-by-step explanation:
Let's recall that formula of the surface area of a pyramid:
S.A. = 1/2*(4 * side of the base * height) + side of the base ²
Replacing with the values provided, we have:
S.A. = 1/2*(4 * 5 * 12) + 5²
S.A. = 1/2 * 240 + 25
<u>S.A. = 145 in²</u>
