Answer:
0.172 square meter of the tank's surface area is in contact with the water.
Step-by-step explanation:
Given:
The dimensions of the water tank are:
Length = 0.2 m.
Width = 0.15 m.
Height = 0.16 m.
Now, to find the area of surface of the tank which is in contact with water.
So, to get the surface area of tank we put formula:
[tex]Surface\ area=2(length\times width + width\times height + height\times length)\\\\Surface\ area=2(0.2\times 0.15+0.15\times 0.16+0.16\times 0.2)\\\\Surface\ area=2(0.03+0.024+0.032)\\\\Surface\ area=2(0.086)\\\\Surface\ area=2\times 0.086\\\\Surface\ area=0.172\ square\ meter.[/tex]
Hence, the surface area of the tank is 0.172 square meter.
Therefore, 0.172 square meter of the tank's surface area is in contact with the water.
