What is the surface area of the figure if s = 3 inches?

A. 108 square inches

B. 54 square inches

C. 90 square inches

Answer 1

$\large\sf\underline{ANSWER:}$

C. 90 square inches

Length (l) = 3 in

Width (w) = 3 in

Height (h) = 6 in

Surface area of figure

= 2 (lw+wh+hl)

= 2 (9+18+18)

= 90 in²
