The sides of a whiteboard are 8 inches by 6 inches. How many 2 inch by 2 inch Post-it notes will be needed to cover the entire whiteboard?

Sagot :

Answer:

12 post-id notes are needed to cover the entire whiteboard.

Explanation:

Sides of a whiteboard are 8 inches by 6 inches.

Area of a whiteboard = length × breadth= 8 × 6 = 48 square inches.

Sides of Post-it notes are 2 inches by 2 inches.

Area of a Post-it note = length × breadth= 2 × 2 = 4 square inches.

Therefore,

Number of Post-it notes needed to cover the entire whiteboard

= Area of a whiteboard ÷ Area of a Post-it note

= 48 ÷ 4

= 12 post-id notes
