Step-by-step explanation:
The volume of the rectangular chocolate bar is 130 cm³.
<h3 /><h3>How to find the volume of rectangular prism?</h3>
volume of the rectangular chocolate prism = lwh
where
- l = length
- w = width
- h = height
Therefore,
l = 0.65 m = 65 cm
h = 2 cm
w = 1 cm
Hence,
volume = 65 × 2 × 1
volume of the chocolate bar = 130 cm³

Answer:
W = integral ( p_w*98.1*(8 - y ) ) . dy , limits = 0 to 8
Step-by-step explanation:
Given:
Dimension of the tank = 5 x 2 x 8
Find:
Set up the integral that would compute the work needed to pump the water out of a spout located at the top of the tank
Solution:
- Make a differential volume (slab) at a depth y with thickness dy and rest dimension the same. We calculate the differential volume as:
dV = 5*2*dy m^3
- Next compute the weight of the differential volume of water:
F_g = p_w*V*g
Where,
p_w : The density of water
g: gravitational constant = 9.81 m/s^2
- Hence, we have:
F_g = p_w*dV*g
F_g = p_w*98.1*dy
- The work done(W) to lift the differential slab of water up:
W = integral ( F_g*(8 - y ) )
- Hence, the integral of work done W is :
W = integral ( p_w*98.1*(8 - y ) ) . dy
- The limits of integration are 0 - 8 m.
