A36 inch by 36 inch ceramic tile shower stall is being installed. how many 4 inch by 4 inch tiles are needed to cover the floor. show the equation and calculation for this question.

You will need 9 4 inch by 4 inch tiles this is just simple math im pretty sure.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
