When you suddenly stand up after lying down for a while, your body may not compensate quickly enough for the pressure changes and you might feel dizzy for a moment.
(a) If the gauge pressure of the blood at your heart is 10.88 kPa and your body doesn't compensate, what would the pressure be at your head, 47.1 cm above your heart?
_____kPa
(b) If the gauge pressure of the blood at your heart is 10.88 kPa and your body doesn't compensate, what would it be at your feet, 1.3x10^2 cm below your heart? Hint: The density of blood is 1060 kg/m3.
_______kPa

Gauge pressure is calculated using the formula p=rho*g*h, where rho is the density in kg/m3, g is gravitational acceleration, and h is height difference in meters. Then calculate pressure difference with p = p1 + p2.
The answers are easy enough to calculate with that info if you're at a college level.
