The area of the room cannot be 64 ft since that is a linear measure, not the measure of an area.
64
120"*120" is 14400 sq. in. 15"*15" is 225 sq. in 14400/225=64 tiles..
Each square tile would be 1.5 ft *1.5 ft or 2.25 sqft Therefore assuming you don't break any tiles you would need 64 tiles. 144 sqft total / (2.25 sqft per tile) = 64
7 ft. = 84 in. 4 ft. = 48 in. 84 x 48 = 4032 sq. in. 4032/64 = 63 tiles
144/(1.5*1.5) = 64 tiles, but if you are using this to determine how many are needed to tile a room, you need to add at least 10% for edging around the room. So, you probably need at least 71 or more tiles.
The area of the room cannot be 64 ft since that is a linear measure, not the measure of an area.
You will need 288 tiles at minimum.
64
120"*120" is 14400 sq. in. 15"*15" is 225 sq. in 14400/225=64 tiles..
64% of 75 is 48 tiles
Each square tile would be 1.5 ft *1.5 ft or 2.25 sqft Therefore assuming you don't break any tiles you would need 64 tiles. 144 sqft total / (2.25 sqft per tile) = 64
Each tile will cover 2 square feet. You have 64 square feet. You will need 32 tiles.
7 ft. = 84 in. 4 ft. = 48 in. 84 x 48 = 4032 sq. in. 4032/64 = 63 tiles
144/2.25=64. 18x18 tile cover 2.25 sq ft area.
You need 0.52, so about a half.because a single 12x12 tile has an area of 144.
Assuming it's a 4x4 wall, 64 tiles
