Below: a sample of 8 questions with answers and explanations so you can see what's on the worksheet before you print. Each question has the correct choice marked and a one-line "why" so kids who get it wrong understand the fix.

Find the circumference of a circle with radius 6. Use π = 3.14.

  1. 37.67
  2. 37.78
  3. 37.68
  4. 37.69

Why: C = 2πr = 2 × 3.14 × 6 = 37.68.

A triangular prism has a triangle base (b=8, h=4) and length 12. What is its volume?

  1. 193
  2. 191
  3. 194
  4. 192

Why: Base area B = ½ × 8 × 4 = 16. V = B × length = 16 × 12 = 192.

Find the volume of a triangular prism whose triangular base has base 9 and height 2, and whose length (depth) is 18.

  1. 161
  2. 164
  3. 163
  4. 162

Why: Base area B = ½ × 9 × 2 = 9. V = B × length = 9 × 18 = 162.

A triangular prism has a triangle base (b=2, h=4) and length 21. What is its volume?

  1. 85
  2. 86
  3. 84
  4. 83

Why: Base area B = ½ × 2 × 4 = 4. V = B × length = 4 × 21 = 84.

A triangular prism has a triangle base (b=4, h=16) and length 7. What is its volume?

  1. 223
  2. 225
  3. 224
  4. 226

Why: Base area B = ½ × 4 × 16 = 32. V = B × length = 32 × 7 = 224.

Find the total surface area of a rectangular prism with length 7, width 17, height 17.

  1. 1054
  2. 1053
  3. 1055
  4. 1056

Why: S = 2(lw + lh + wh) = 2(119 + 119 + 289) = 1054 square units.

Find the total surface area of a rectangular prism with length 2, width 8, height 5.

  1. 132
  2. 134
  3. 131
  4. 133

Why: S = 2(lw + lh + wh) = 2(16 + 10 + 40) = 132 square units.

A box is 20 × 16 × 7. What is its total surface area?

  1. 1143
  2. 1146
  3. 1145
  4. 1144

Why: S = 2(lw + lh + wh) = 2(320 + 140 + 112) = 1144 square units.
