4-ft x 8-ft = 32 square feet in each sheet400/32 = 121/2 sheets
Assuming it's 4x8 inches, then one brick = 1/3 feet * 2/3 feet, so the area of a brick is 2feet2/9. 120 feet2/(2feet2/9) = 540 bricks
That depends - whether your 4x8 bricks are in centimetres, metres, inches or feet.

Just multiply the two numbers together. This means it covers 32 square feet.
how many 8*4 sheets in 2056 m2
The answer depends on the units used for 4x8 which are unspecified. The answer will vary according to whether those units are inches, metres, parsecs, etc.
For 80 square feet you will need a 360 4" x 8" bricks.
