Expert Answer

Weight of the block = 8×10 = 80N
Pressure when block placed on side 100 cm and 50 cm
P = F/A = 80/(1×0.5) = 160 Pass
Pressure when block is placed on side 50 cm and 20 cm
P= F/A = 80/(0.5×0.2) = 800 Pa
Pressure when block is placed on side 20cm and 100cm
P = F/A = 80/(0.2×1) = 400 Pa
