A square table is to be covered with small square ceramic tiles. The table has an area of 4 square feet. How many tiles are needed if each tile measures 3 inches on one side?
Thank you for the opportunity to help you with your question!
3 inch on each side gives us 9 square inches per each tile. we can convert the ft into inches or inches into fts in order to be able to divide through.
one foot is equal to 12 inches!
so 3 inches would be 0.25 ft
area of the sqiare tile in feets= 0.25^2
4ft^2........of the table
divide by 0.0625 ft^2 of the tiles
