A patio measures 12 feet by 14 feet. How many 8-inch-square paving stones are needed to pave the patio?

A. 21
B. 252
C. 378
D. 168

can someone explain that to me

thanks

• quick math -

12 x 14 =168 square feet.

If the pavers were 1 foot by 1 foot we would need 168 pavers

BUT.. your paver is 8 inches which is 8/12 or 2/3 of a foot.

It is 2/3 times 2/3 or 4/9 square ft

168 divided by 4/9

which is the same as 168 times 9/4

That will get you to 378.
