Let’s go through each problem one by one. Remember, we’re looking for multiplication problems — but there’s one “trick” problem that is NOT a multiplication problem. We’ll figure out which one it is as we solve them.

Problem 1:
A scale model of a Boeing 747 is 7m long. The real plane is 10 times longer. How long is the actual plane?
→ Multiply: 7 × 10 =
70 meters
---
Problem 2:
A box of eggs holds 6 eggs. If I had 20 full boxes, how many eggs would I have?
→ Multiply: 6 × 20 =
120 eggs
---
Problem 3:
A pack of 8 pens costs me $10. I buy 12 packs. How many pens have I bought?
→ We only care about number of pens, not cost.
→ Multiply: 8 × 12 =
96 pens
---
Problem 4:
A box of chocolates contains 30 chocolates. How many chocolates in 4 boxes?
→ Multiply: 30 × 4 =
120 chocolates
---
Problem 5:
How many days in 20 weeks?
→ There are 7 days in a week.
→ Multiply: 7 × 20 =
140 days
---
Problem 6:
A paperclip is made from 10cm of wire. How many paperclips could be made from 70cm of wire?
→ This is division! You’re splitting 70cm into groups of 10cm.
→ Divide: 70 ÷ 10 =
7 paperclips
✔ This is the “trick” problem — it’s NOT multiplication!

Problem 7:
A ream contains 500 sheets of paper. How many sheets in 2 reams?
→ Multiply: 500 × 2 =
1000 sheets
---
Problem 8:

→ Multiply: 60 × 3 =
180 seconds
