Expert Solution
Step 1

Given:

Mass of rectangular gasoline when it is full of gasoline is m=50 kg

Length of tank is l=0.900 m

Width of tank is w=0.500 m

Density of gasoline is ρ=6.80×102 kg/m3

Note:

1 N=1 kg·m/s2

1 Pa=1 N/m2

Find:

(a) The height of tank.

(b) Pressure exerted on the bottom of tank.
