VOLUNTEER TRAINING FOR DISADVANTAGED IN MATHS – QUESTION 4 : A 4 × 4 grid is made using 40 matches. How many matches are needed to construct a 10 × 10 grid?
VOLUNTEER TRAINING FOR DISADVANTAGED IN MATHS – ANSWER 4 : 220. For 10 x 10 grid : Every vertical line has 10 matches, then total vertical lines = 10 + 1 = 11. Every horizontal line has 10 matches, then total horizontal lines = 10 + 1 = 11. So total matches required = 2 x 10 x 11 = 220.
