Answer:
The surface area of the fish tank is:
230 square feet
Step-by-step explanation:
Let l denote the length of tank
and w denote the width of the tank
and h denote the height of the tank.
from the figure we have:
l=10 feet, w=5 feet and h=6 feet
Now, we need to find the surface area of tank such that the tank does not has a cover this means the top face is not there.
Hence, the surface area is calculated as follows:
[tex]Surface\ Area=l\times w+2\times l\times h+2\times w\times h\\\\\\Surface\ Area=10\times 5+2\times 10\times 6+2\times 5\times 6\\\\\\Surface\ Area=50+120+60\\\\\\Surface\ Area=230\ \text{square\ feet}[/tex]
