Answer: Weight truck+load = 29.4×
N
Explanation: When an object floats in a fluid, there is an upward force, caused by the liquid, acting on the object that opposes the weight of the immersed object. This force is called <u>Buyoyant</u> <u>Force</u> and is determined by:
B = d*V*g
where
d is density of the fluid;
V is volume of liquid displaced due to the immersed object;
g is acceleration due to gravity;
For the truck, the system is in equilibrium, which means buyoyant force is equal weight. Then:
Volume displaced is
V = 10*8*0.0375
V = 3 
Density of water: 1000kg/

= 1000*3*9.8
= 29.4×
N
The weight of the truck and the load is 29.4×
