How many 16x16 square inch tiles do i need to cover 40 square feet?
40 square feet = 40*12*12 square inches = 5760 sq inches No of 16*16 tiles = 5760/(16*16) = 22.5. So 23 tiles will do. BUT if this is a practical question rather than a maths question, you will also need to allow for wastage.

How many inches in 23 square feet?
Your units do not make sense with respect to one another. Inches are units of length while square feet are units of area. I will assume that you mean how many square inches are in 23 square feet. 1 foot = 12 inches therefore 23 ft^2*(12 inches/1 foot)^2 this is your equation to convert to square inches. notice that the ft^2 cancel with the foot^2 in the parentheses. so 23*12^2 or 23*144 = 3312 in^2 is your answer
