Answer 1

Answer:

Disagree

Step-by-step explanation:

The surface area of the given prism consists of the following parts;

1) The area of the top and bottom right triangles, A₁, and A₂, which are given as follows;

A₁ = A₂ =  (1/2) × 5 × 12 = 30

2) The area of the left rectangle, A₃ = 5 × 8 = 40

3) The area of the rear rectangle, A₄ = 13 × 8 = 104

4) The area of the front rectangle, A₅ = 12 × 8 = 96

∴ A = A₁ + A₂ + A₃ + A₄ + A₅

A = 30 + 40 + 104 + 96 + 30 = 300

Jim B 65 + 65 + 104 + 96 + 40 = 370

The surface area of the triangular prism, A = 300 cm²

Jim-Bob's calculation contains two errors

1) 65 + 65 + 104 + 96 + 40 = 370 ≠ 270

2) The area surface area of the triangular prism = 300 cm² not 270 cm²  

and therefore, disagree with his calculation.
