To cover the floor - 40.
24 inch by 15 inch = 2 feet by 1.25 feet.
So, you will get five blocks the 24 inch way (10/2 = 5), and eight the 15 inch way 10/1.25 = 8).
5 x 8 = 40.
Since you did not give a) the height of the room and b) the thickness of the blocks, we must assume you wanted only one layer on the floor.

12 x 12 blocks (assumed as 12 inch x 12 inch) That means the blocks are 1 square foot each Hence to cover 240 square feet area, you would need 240 blocks
Assumption: 6 x 6 is using inches as the unit (half a foot) and a 4 foot board means 4 square feet of board. Each square foot of board can be cut into four half foot x half foot pieces. Therefore, the 4 foot board would be able to make 16 half foot x half foot (6 inch x 6 inch) blocks.
The answer will depend on the width of the fabric as well as the units used for 10x10. It should be blindingly obvious to anybody that the answers for 10 inch x 10 inch will be quite different to 10 cm x 10 cm.
There 12 inches to a foot, so 120 tenths of an inch to a foot.
