Question

What is the surface area in square centimeters of the figure shown below?

11 cm
6 cm
4 cm

Answer 1

268 cm²

Explanation:

Surface area = (front + back + left side + right side + top + bottom) areas

since pairs of areas are the same (front back, left rigth, top bottom)

Surface area = (2 · front + 2 · left side + 2· top) areas

= 2 · 11 · 4 + 2 · 11 · 6 + 2 · 4 · 6

= 268 cm²
