Answer:

32 yd^2

Step-by-step explanation:

Ignore rounded approximations (i.e. 2.66, 1.33). For all calculations, use fractions and EXACT values.

This prism has 6 surfaces:

  1. Front: 3 x 2.66 = 8
  2. Back: 3 x 2.66 = 8
  3. Top: 3 x 1.33 = 4
  4. Bottom: 3 x 1.33 = 4
  5. Side: 1.33 x 2.66 = 4
  6. Side: 1.33 x 2.66 = 4

Total SA: 8(2) + 4(4) = 32 yd^2
