8 bamboo rods are needed to make a bullock cart. How many bamboo rods are needed for 23 carts?

Correct Answer

Given: 8 bamboo rods per bullock cart 23 carts

Formula: Total rods = Number of carts × Rods per cart

Substitution: Total rods = 23×823 \times 8

Calculation: Break 23 into 20 + 3 20×820 \times 8 = 160 rods 3×83 \times 8 = 24 rods Total = 160 + 24 = 184 rods

Answer: 184 bamboo rods are needed for 23 carts.

Explanation

The chapter uses the same method for larger numbers. For 23×823 \times 8: Break 23 into 20 + 3. Then 20×820 \times 8 = 160 and 3×83 \times 8 = 24. Total = 160 + 24 = 184 bamboo rods. This demonstrates multiplication using place value decomposition.

Solution Steps

  1. Step 1: Total rods = 23 carts × 8 rods per cart

  2. Step 2: Break 23 into 20 + 3

  3. Step 3: 20×820 \times 8 = 160 rods

  4. Step 4: 3×83 \times 8 = 24 rods

  5. Step 5: Total = 160 + 24 = 184 rods
