WE KNOW THAT,
PRESSURE=FORCE×AREA⁻¹
HERE,
FORCE=45 Kg
AREA=(15+15)CM=0.3 METER
PRESSURE=45/0.3
=450/3
=150 N/m²
PRESSURE=FORCE×AREA⁻¹
HERE,
FORCE=45 Kg
AREA=(15+15)CM=0.3 METER
PRESSURE=45/0.3

SWAGGERT:
I tink ur anser is rong, as pressure is written as pascal.
n i tink dat it is 15,000 or 1,50,000
i am not sure
PASCAL = N/METRE2 THEY BOTH ARE SAME
AND HERE W=M*10 IS RONG
vat is w?
9.8 is the acceleration due to gravity
10 is an estimate
so, f=mass × m, i.e. mass × 10
NO NO YOU TAKE IT WRONG HERE THE MASS ITSELF IS THE WEIGHT , YOU SUPPOSE CAN ANYONE HAVE MASS 450 Kg CAN SOMEONE CAN ASK SUCH RIDICULOUS ANSWER
