Surface area (cylinder side) = circumference × length. Diameter = 8 in = 0.667 ft. Circumference = πd = 3.14 × 0.667 ≈ 2.095 ft. Multiply by length: 2.095 × 20 = 41.9 ft². Option B is correct. CAST Graphic Arithmetic requires converting inches to feet before calculating surface areas.

The passage emphasizes lockout as essential to protect workers. Option B is correct. CAST Reading Comprehension focuses on safety-critical workplace practices.

1 hour = 3,600 seconds. Multiply: 3.2 × 3,600 = 11,520 seconds. Option C is correct. CAST Mathematical Usage reinforces accurate time conversions.

Convert thickness: 4 in = 0.333 ft. Volume = 10 × 8 × 0.333 ≈ 26.7 ft³. Closest answer is D (26 ft³). CAST Graphic Arithmetic requires careful unit conversions from inches to feet.

Torque = Force × Distance. Rearranged: Force = Torque ÷ Distance. 120 ÷ 2 = 60 lb. Option C is correct. CAST Mathematical Usage integrates formulas with unit application, testing mechanical awareness alongside arithmetic.
