The total volume of water in the tank after 3 mins 24.75 gallons.
<h3>New volume of water in the tank</h3>
The new volume of water that entered into the tank is calculated as follows;
V₁ = 0.1 L/sec x (3 x 60 s)
V₁ = 18 L
<h3>Volume of water in liters to gallon</h3>
1 liter = 0.264 gallons
18 Liter = ?
= 18 x 0.264
= 4.75 gallons
<h3>Total volume of water in the tank after 3 mins</h3>
V = 20 gallons + 4.75 gallons
V = 24.75 gallons

The surface area of the triangular prism is of 140 cm².
<h3>What is the surface area of a prism?</h3>
It is the sum of the areas of all faces of a prism. In this problem, the prism has these following faces:
- One rectangle of dimensions 8 cm and 6 + 4 + 5 = 15 cm.
- Two right triangles with sides 4 cm and 5 cm.
For a rectangle, the area is given by the multiplication of the dimensions, hence:
Ar = 8 x 15 = 120 cm²
For each right triangle, the area is given by half the multiplication of the sides, hence:
At = 2 x 0.5 x 4 x 5 = 20 cm².
Then the surface area of the prism is:
S = 120 cm² + 20 cm² = 140 cm².
