### How many 30x24 inch blocks would it take to cover the bottom area of an 8x10 feet object?

Determine the number of square inches of the blocks surface
Multiply 30 inches x 24 inches = 720 square inches per block
NOW find the number of square inches in an area 8 foot x 10
foot
Multiply 8 foot x 10 foot = 80 square feet
To find the square inches of a square foot, you multiply 144
inches (12 inches by 12 inches = 144 inches) by the number of
square feet, thus,
80 square feet x 144 square inches = 11,520 square inches
In order find the number of blocks you will need to cover the
area,
Divide the number of square inches of area to be covered by the
number of square inches per block
11,520 square inches divided by 720 square inches per block = 16
blocks needed to
fill an area 8 foot x 10 foot.
