Answer:
Sally needs
140 tiles
Step-by-step explanation:
Area of each tile = 1ft * 1ft = 1ft²
Area of the bathroom floor = 20ft * 7ft = 140ft²
Then:
140ft² / 1ft² = 140
i think if i did my math right its 140
$ 3.50 per lb * 1 1/2 lbs
3.50 per lb * 1.5 lbs = 5.25
It will cost $5.25
27.
54 = 2 * 3 * 3 * 3.
3 occurs 3 times so the perfect cube is 27.
678 cu. in.
hope this helps!
