Solution

The correct option is B
2000 Pa

The bottom area of the block, $A r e a = l \times b = 1.5 m \times 1 m = 1.5 m^{2}$
The weight of the block as a force, $F = w = m \times g = 300 \times 10 = 3000 N$
Pressure is given by, $P = \frac{F}{A} = \frac{3000 N}{1.5 m^{2}} = 2000 P a s c a l$

The bottom area of the block, $A r e a = l \times b = 1.5 m \times 1 m = 1.5 m^{2}$
The weight of the block as a force, $F = w = m \times g = 300 \times 10 = 3000 N$
Pressure is given by, $P = \frac{F}{A} = \frac{3000 N}{1.5 m^{2}} = 2000 P a s c a l$
