Halloween Math & Reading — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. A candy box is 8 inches long, 5 inches wide, and 3 inches tall. What is its volume?
A) 120 cubic inches
B) 96 cubic inches
C) 142 cubic inches
D) 158 cubic inches
Volume of a rectangular box equals length times width times height: 8 × 5 × 3 = 120 cubic inches.
2. A store sells 400 masks. 45% are witch masks, 30% are vampire masks, and the rest are ghost masks. How many ghost masks are there?
A) 80
B) 120
C) 100
D) 60
Witch and vampire masks together make up 45% + 30% = 75% of the masks, leaving 25% as ghost masks. 25% of 400 is 100 ghost masks.
3. Evaluate: 4 × (6 + 3) − 12 ÷ 4. What is the answer?
A) 33
B) 36
C) 30
D) 27
Following order of operations, parentheses come first: 6 + 3 = 9. Then multiply and divide left to right: 4 × 9 = 36 and 12 ÷ 4 = 3. Finally subtract: 36 − 3 = 33.
4. A rectangular haunted maze is 50 meters long and 30 meters wide. A path around the outside edge is 2 meters wide. What is the area of just the path?
A) 304 sq m
B) 296 sq m
C) 320 sq m
D) 288 sq m
The full maze area is 50 × 30 = 1500 sq m. The inner rectangle (after removing the 2 m path on every side) is 46 × 26 = 1196 sq m. The path is the difference: 1500 − 1196 = 304 sq m.
Part B: Fill in the Blank
Write the correct answer on each line.
1. A coffin-shaped box is 6 ft long, 2 ft wide, and 2 ft tall. Its volume is 24 cubic feet.
Multiply length, width, and height to find volume: 6 × 2 × 2 = 24 cubic feet.
2. A costume originally costs $60. With a 20% discount, the sale price is $48 .
A 20% discount on $60 saves 0.20 × 60 = $12, so the sale price is $60 − $12 = $48.
3. Evaluate: 5 + 3 × 8 − 2. The answer is 27.
Order of operations puts multiplication before addition and subtraction: 3 × 8 = 24, so the expression becomes 5 + 24 − 2 = 27.
4. A pumpkin weighs 4.6 kg. Three identical pumpkins weigh 13.8 kg total.
Three identical pumpkins together weigh 3 × 4.6 = 13.8 kg. Multiplying by 3 is the same as adding 4.6 + 4.6 + 4.6.
5. If 710 of 90 trick-or-treaters wore costumes, then 63 wore costumes.
Seven tenths of 90 means (7 ÷ 10) × 90, or equivalently 7 × 9 = 63 trick-or-treaters in costume.
