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.
- 37.67
- 37.78
- 37.68 ✓
- 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?
- 193
- 191
- 194
- 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.
- 161
- 164
- 163
- 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?
- 85
- 86
- 84 ✓
- 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?
- 223
- 225
- 224 ✓
- 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.
- 1054 ✓
- 1053
- 1055
- 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.
- 132 ✓
- 134
- 131
- 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?
- 1143
- 1146
- 1145
- 1144 ✓
Why: S = 2(lw + lh + wh) = 2(320 + 140 + 112) = 1144 square units.
