CONVERSION FACTOR:
- According to this question, Murthry's dog house floor has an area of approximately 4 square meters. He is purchasing tiles that are 1 square cm each.
- To calculate the number of tiles needed by Murthry's to cover the dog house, we need to convert metres² to centimeters² as follows:
- 1 square centimetre = 0.0001 square metre
- 4 sq m = 4 ÷ 0.0001 = 40000sq cm.
- This means that 40000cm² ÷ 1cm² = 40000 tiles will be needed to cover the entire floor of the dog house.
