Don't know whether you're talking same units or feet and inches, but here goes anyway:
If you mean 16 x 12 inches and 4 x 8 inches then 16 x 12 needs 3 across and 2 down ie 6 tiles.
If you mean 16 x 12 feet and 4 x 8 inch tiles you will need 24 across and 36 down ie a total of 864 tiles.
Eight squares are needed.
12*12 = 144
320
There are 9 squares I can see 12 squares in an array of 2 * 4 squares
2400 tiles if you don't get any extra
Eight squares are needed.
It depends on how large the squares are. If they are 12" x 12" it would take 108 of them.
105
12*12 = 144
To determine the number of squares of shingles needed to cover a 24x50 roof, first calculate the total area of the roof: 24 feet x 50 feet = 1,200 square feet. Since one square of shingles covers 100 square feet, you would divide the total area by 100. Therefore, you would need 12 squares of shingles to cover the roof.
How many squares come in one box. If the squares are 40" x 40", you need 12 of them. You will have scraps left over.
12 square feet
210 of them.
