Aflooring company ships 13x13 inch tile in boxes of 11 tiles each, on pallets containing 40 boxes (check work required. )

a) how many square feet does each box contain?
b) how many square feet will a pallet of tile cover?

Each tile cover an area of 13 in*13 in= 1.08 ft *1.08 ft= 1.17 square feet.

A) Each box contains 11 tiles, each of which covers 1.17 square feet.

So the area each box covers is 11*1.17 square feet=12.87 square feet

B) A pallet contains 40 boxes, each of which covers 12.87 square feet, 

so one pallet covers 40*12.87 square feet=514.8 square feet.

A) 12.87 square feet

B) 514.8 square feet.

I’m not sure about that
